A facile one-step microwave-assisted chemical method has been successfully used for the synthesis of Cu2O/reduced graphene oxide (RGO) composites. Photocatalytic CO2 reduction was then investigated on the junction under ambient conditions. The RGO coating dramatically increases Cu2O activity for CO2 photoreduction to result in a nearly six times higher(More)
CO2 photoreduction over KTaO3 photocatalysts in water has been investigated. Both reduction (mainly carbon monoxide and hydrogen) and oxidation products (oxygen) were simultaneously detected in the absence of cocatalysts, sacrificial reagents and electrical bias. KTaO3 (KTO) samples were synthesized by solid-state reaction (SSR-KTO) and solvothermal methods(More)
