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 Development of three-dimensional nickel-cobalt oxide nanoflowers for superior photocatalytic degradation of food colorant dyes: Catalyst properties and reaction kinetic study, published in 2021-11-09, which mentions a compound: 25956-17-6, Name is Sodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfonatophenyl)diazenyl)naphthalene-2-sulfonate, Molecular C18H14N2Na2O8S2, Category: pyrazoles-derivatives.
In this work, we present three-dimensional flower-like nickel-cobalt oxide (F-NCO) nanosheets developed in a facile, eco-friendly hydrothermal route to apply as photocatalysts for food colorant Allura Red AC dye removal under light illumination. Using Brunauer-Emmett-Teller anal., it was found that the F-NCO nanosheets displayed a surface area of ∼53.65 m2/g and a Barrett-Joyner-Halenda pore size of ∼14 nm, which was also confirmed by the calculated crystallite size of ∼15 nm using powder X-ray diffraction (XRD) anal. From Williamson-Hall anal. of XRD spectra, F-NCO nanosheets revealed a crystal-lattice strain of ∼3.42 × 10-3 and a dislocation d. of ∼4.397 × 1015 lines/m2 in the crystal structure. Transmission electron microscopy anal. revealed that F-NCO nanosheets accumulated to form flower-like nanostructures of <100 nm length with a d-spacing of ∼2.6 Å, which is attributed to the (311) crystallog. plane (α = γ = β = 90°, a = b = c = 8.110 Å, JCPDS Number 00-020-0781) of the cubic phase. The F-NCO nanosheets exhibited an excellent photocatalytic efficiency of ∼94.75% in ∼10 min with sodium borohydride under UV light. The Langmuir-Hinshelwood model determined pseudo-first-order reaction kinetics of dye degradation using the vs. time plot. The kinetic study produced a first-order rate constant (k) of ~0.219 min-1, resulting in ∼3.16 min half-life (t1/2) for the F-NCO-catalyzed degradation reaction. Thus outstanding photocatalytic performance of F-NCO nanosheets would display their huge potential for organic-pollutant removal from water with exceptional recyclability for wide research applications in the future.
