New modeling of AgFeNi2S4-graphene-TiO2 ternary nanocomposite with chelate compounds and its photocatalytic reduction of CO2

The most efficient method of converting CO2 to hydrocarbon fuels is a photocatalyst-based process, in which the charge transfer and recombination rate electron–hole pair are important parameters that determine catalytic activity photocatalyst. Novel structured ternary photocatalyst keeps more advantage than binary material because it has strong light absorption enhanced photocatalytic potency. Based on abovementioned superiority, our study proposes new model nanocomposite synthesized by solvothermal methods consisting graphene, TiO2, chalcogenide-quaternary nanostructures. high surface area 2D-structured graphene can be bridge between semiconductor quaternary, increases absorption, enhances photogenerated transfer. preparation quaternary was based metallic citrate polymerization used ethylene glycol (C2H6O2) citric acid (C6H8O7) as chelate cations. morphology carrier properties were analyzed physical characterization equipment, determined reduction experiment with different electron-scavengers electron-donor scavengers experiment. final yield methanol under UV 8.62% 7.23%, visible 6.25% 5.92%, respectively. In addition, stability reusability six-times cycling test without loss formation evolution. confirmed had stability, this confirms newly modeled nanomaterials active materials for applications environmental pollution removal production fuels.
