Novel Micro and Nanostructure of a AgCuInS(2)–Graphene–TiO(2) Ternary Composite for Photocatalytic CO(2) Reduction for Methanol Fuel

[Image: see text] Photocatalytic CO(2) reduction into hydrocarbon fuels over photocatalysts has hypothetical and reasonably developed into a trendy exploration topic. In this study, the progress of the quaternary nanocomposite containing a graphene-based catalyst was reported; this was fabricated using the hydrothermal technique. The analysis of physical characteristics of the nanocomposite confirmed the interaction between all parts. The quaternary nanocomposite containing the graphene-based catalyst was utilized for carbon dioxide reduction to methanol (CH(3)OH) under light irradiation. Titanium dioxide (TiO(2)) and the quaternary nanocomposite of AgCuInS(2) were monotonously spread on the graphene exterior. This nanomaterial showed superior activity compared with TiO(2) and the binary composite for CO(2) conversion, and the obtained result indicates that the synthesized ternary composite enhaces the properties of the photocatalyst in the reduction process.
