摘要：
Copper oxide (I) nanoparticles decorated on nitrogen-doped carbon (N-C) rod-shaped core-shell nanostructure have been successfully prepared. The nanostructures have been developed by the reduction of Cu2+ with ascorbic acid over Fe3O4@N-C rod-shaped core-shell nanostructure followed by aerobic oxidation of copper nanoparticles. Furthermore, the photocatalytic activity of Fe3O4@N-C/Cu2O nanostructure was evaluated in selective CO2 reduction and methanol was observed as the main product over Fe3O4@N-C/Cu2O. The photocatalytic activity of Fe3O4@N-C/Cu2O for CO2 reduction was found to be about four times higher than that of Fe3O4@Cu2O photocatalyst, which might be due to the enhancement of visible light absorption and facilitating the separation of photogenerated electron-hole pairs.
