Novel Micro and Nanostructure of a AgCuInS2–Graphene–TiO2 Ternary Composite for Photocatalytic CO2 Reduction for Methanol Fuel

摘要

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.
