Developing cost-effective catalysts with superb activity and stability to alc. electro-oxidation is a decisive factor toward the progress of direct alc. fuel cells (DAFCs). Rationally utilizing the architectural and surface microstructural sensitivity of nanocatalysts can significantly increase their electrocatalytic properties. Here, we report an appropriate route that allows the fabrication of ultrafine PtFeSn nanowires (NWs) with tunable compositions Interestingly, the addition of Sn reconstructed the surface microstructures, making ultrafine 1D NWs rich in a large number of surface protuberances, which may facilitate the oxidation of ethanol and methanol. Impressively, further catalytic studies demonstrate that all the PtFeSn NWs exhibit excellent catalytic capabilities for ethanol oxidation reaction (EOR) and methanol oxidation reaction (MOR), and display composition-related electrocatalytic activity with Pt1Fe0.20Sn0.46 NWs, possessing the highest activity for EOR and MOR. In addition, the trimetallic PtFeSn NWs exhibit significant meliorative durability relative to PtFe NWs and com. Pt/C. The superb electrocatalytic performance is ascribed to its one-dimensional (1D) structure, at.-level fine diameter, synergistic effect among Pt, Fe, and Sn components and abundant protuberances on the surface. Thus, this study highlights the significance of accurate structure- and surface-controlled Pt-based NWs for electrocatalysis and provides a universal approach for designing multi-component catalysts.

Safety of Tin(II) oxalate. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about Na2SnO3 as a novel anode for high performance lithium storage and its electrochemical reaction mechanism. Author is Lu, Fan; Zeng, Weiying; Lin, Haifeng; Liu, Shengzhou; Tian, Xiaoqing; Yang, Jie; Li, Jumei; Yang, Yin.

Herein, Na2SnO3 is employed as an anode for rechargeable Li ion battery (LIB). The authors thoroughly studied the electrochem. performance of Na2SnO3 in comparison with the most commonly used Sn based oxides, such as SnO2 and Li2SnO3. Na2SnO3 is greatly superior to SnO2 and Li2SnO3 in terms of capacity, cycling stability and rate capability. Impressively, Na2SnO3 presents favorable specific capacity of 480 mA h g-1 at c.d. of 200 mA g-1 after 100 cycles and still delivers a capacity of 439 mA h g-1 at extremely large c.d. of 1000 mA g-1, which are leading the performance in anodes for LIBs. Ex situ SEM anal. of anodes after different cycles revealed the surface microstructure of anodes plays a critical role in determining cycling stability. The SEM results show big cracks on the surface of electrode for SnO2 after less 15 cycles and for Li2SnO3 after more 100 cycles, resulting from their severe volume change during charging-discharging process. However, Na2SnO3 electrode exhibits uniform surface morphol. after 100 cycles. It is concluded the Na2O” intrinsic matrix of Na2SnO3 combining with Li2O” formed from the conversion reaction can act as a mixture buffering matrix that contributes to keeping the electrochem. formed nanoscale Sn particles apart and preventing their agglomeration during Li-Sn alloy formation and decomposition, thus inhibiting the volume expansion and the capacity fading by maintaining the electrode integrity. The electrochem. reaction mechanism of Na2SnO3 with Li was studied by ex situ XRD technique. The findings in this study provide a new valuable anode for high-performance LIBs and an insightful viewpoint of developing anode materials with high electrochem. performance by introducing the electrochem. inactive intrinsic matrix.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Tin(II) oxalate(SMILESS: O=C([O-])C([O-])=O.[Sn+2],cas:814-94-8) is researched.HPLC of Formula: 25956-17-6. The article 《Enhanced gas selectivity induced by surface active oxygen in SnO/SnO2 heterojunction structures at different temperatures》 in relation to this compound, is published in RSC Advances. Let’s take a look at the latest research on this compound (cas:814-94-8).

The development of heterojunction structures has been considered as an important step for sensing materials. In this report, 3D hierarchical SnO-SnO2 heterojunction structures were synthesized and developed via simple one-pot hydrothermal synthesis without any extra processes. The prepared 3D samples exhibit high sensitivity, benefiting from the synergistic effects of SnO and SnO2. Interestingly, SnO-SnO2 hybrid structures exhibited distinctly different sensitivities at 180 and 280°C, and the sensitivity can achieve values of 47.69 and 41.56 toward ethanol and acetone, resp., at concentrations of 100 ppm. A mechanistic anal. of the sensitivity and concentration-dependence revealed that the oxygen species on the surface were O- and O2- at different temperatures Therefore, the temperature selectivity of the sample may be due to the different activities of the active oxygen species. Moreover, the composition also shows excellent stability at operating temperatures The high sensing sensitivity and selectivity is promising for practical VOC gas detection; this also offers a new perspective for the design of multifunctional sensing materials.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Shape- and size-dependent desorption kinetics and surface acidity of nano-SnO2, published in 2022, which mentions a compound: 814-94-8, Name is Tin(II) oxalate, Molecular C2O4Sn, Formula: C2O4Sn.

The desorption kinetic parameters (the desorption activation energy (Ed) and the desorption pre-exponential factor (A)) and the surface acidity (the strength and number of acid sites) of spherical and octahedral nano-SnO2 with different particle sizes for NH3 were measured by a temperature-programmed desorption method. Afterwards, the shape and size dependence of the desorption kinetic parameters and surface acidity of nano-SnO2 were discussed. The results show that shape and size have significant influences on the desorption kinetics and surface acidity of nano-SnO2. For the desorption on spherical or octahedral nano-SnO2, Ed, ln A, and the strength and number of acid sites increase with decreasing particle size. When the diameter is larger than 20 nm, Ed, ln A, and the number of surface acid sites are linearly related to the reciprocal of the particle size, resp. For different shapes of nano-SnO2 with the same equivalent diameter, the desorption kinetic parameters of octahedral nanoparticles are larger than those of spherical ones, i.e., Edoctahedron > Ed sphere and ln A octahedron > ln A sphere. The influence mechanism of shape and size on the desorption kinetic parameters of nano-SnO2 can be attributed to the influence of shape and particle size on the surface acidity of nano-SnO2.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Lin, Zhijie; Liang, Yucang; Zeng, Yiming; Chen, Xuan; Liu, Manmen; Dai, Pinqing; Chen, Jialin; Sun, Xudong researched the compound: Tin(II) oxalate( cas:814-94-8 ).COA of Formula: C2O4Sn.They published the article 《Morphology-tunable synthesis and formation mechanism of SnO2 particles and their application in Ag-SnO2 electrical contact materials》 about this compound( cas:814-94-8 ) in Ceramics International. Keywords: silver tin oxide elec contact material nanoparticle morphol. We’ll tell you more about this compound (cas:814-94-8).

SnO2 powders with four distinct morphologies of prismoids, hollow rhomboidal tubes, solid rhomboidal rods, and needles have been prepared through morphol.-conserved transformation from SnC2O4 precursors. The SnC2O4 precursors were synthesized by a facile oxalate precipitation method. A controllable periodic bond chain (PBC) growth was found to be critical for the formation of these SnC2O4 samples. In the case of forward titration, SnC2O4 prismoids were generated because the formed Sn3O(OH)2SO4 was attached on {1 01} polar facets and inhibited the PBC growth along the c axis. By contrast, in the case of reverse titration, SnC2O4 samples preferably formed one-dimensional shapes. Dissolution and ripening were observed during the formation of hollow tubes in the case of low molar ratio of Sn2+ to C2O2-4. Further, the formation of SnC2O4 needles was ascribed to the selective coordination of polyvinylpyrrolidone (PVP) on the side surface. The as-prepared SnO2 powders were used as reinforcement of Ag-SnO2 elec. contact materials, and a good adhesion was observed at the Ag (111)/SnO2 (200) interface. Further, the characterization results revealed that the sample reinforced by SnO2 tubes (with one-dimensional shape and hollow structure) had the lowest degradation rate under cathode arc erosion, which might be attributed to its good resistance to the dual action (heat and force) of cathode arc.

Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about Preparation and study of morphology of mesoporous anodic films grown on tin foil. Author is Vasilieva, T. A.; Uvarov, N. F.; Bokhonov, B. B..

Mesoporous anodic layers were obtained on high-purity tin foils in electrolyte of two types: 0.3 M oxalic acid and 1 M NaOH in various anodizing modes. It was demonstrated that in both cases at low voltages below 4 V barrier films form. In acidic electrolyte the formation of tin (II) oxalate was observed whereas in basic electrolytes SnO2·nH2O seems to be formed. At intermediate voltage values from 4 to 8 V mesoporous films may be obtained with average size of pores of 20-40 nm, mesopores are rather uniformly distributed along the surface. It was found that in contrast to alumina anode films no linear dependency between pore diameter and voltage was observed at anodizing of tin foil. At voltages above 8 V and/or long-term anodization the film cracks and the film split to sep. islands.

COA of Formula: C2O4Sn. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Tin(II) oxalate, is researched, Molecular C2O4Sn, CAS is 814-94-8, about A new lithium diffusion model in layered oxides based on asymmetric but reversible transition metal migration. Author is Ku, Kyojin; Kim, Byunghoon; Jung, Sung-Kyun; Gong, Yue; Eum, Donggun; Yoon, Gabin; Park, Kyu-Young; Hong, Jihyun; Cho, Sung-Pyo; Kim, Do-Hoon; Kim, Hyungsub; Jeong, Eunsuk; Gu, Lin; Kang, Kisuk.

Lithium-rich layered oxides (LLOs) are considered promising cathode materials for lithium-ion batteries because of their high reversible capacity, which is attributed to the exploitation of the novel anionic redox in addition to the conventional cationic redox process. Transition metal (TM) migration, which is known to be the main cause of the voltage decay in LLOs, is now understood to also be the critical factor triggering anionic redox, although this origin is still under debate. A better understanding of the specific TM migration behavior and its effect during charge/discharge would thus enable further development of this class of materials. Herein, we demonstrate that the unique TM migration during charge/discharge significantly alters the lithium diffusion mechanism/kinetics of LLO cathodes. We present clear evidence of the much more sluggish lithium diffusion occurring during discharge (lithiation) than during charge (de-lithiation), which contrasts with the traditional lithium diffusion model based on simple topotactic lithium intercalation/deintercalation in the layered framework. The reversible but asym. TM migration in the structure, which originates from the non-equivalent local environments around the TM during the charge and discharge processes, is shown to affect the lithium mobility. This correlation between TM migration and lithium mobility led us to propose a new lithium diffusion model for layered structures and suggests the importance of considering TM migration in designing new LLO cathode materials.

After consulting a lot of data, we found that this compound(814-94-8)COA of Formula: C2O4Sn can be used in many types of reactions. And in most cases, this compound has more advantages.
