A facile method was used to fabricate 3D nitrogen-doped graphitic carbons with embedded core-shell nanoparticles. These materials showed excellent photocatalytic activity and could be used for the design and synthesis of high-efficiency core-shell photocatalysts.
A facile polymer thermal treatment method has been employed to fabricate 3D honeycomb-like nitrogen-doped graphitic carbons (N-GCs) with embedded core-shell Cu@Cu2O nanoparticles (NPs). The 3D honeycomb-like N-GC architectures can not only serve as an excellent carrier for core-shell Cu@Cu2O NPs, but also provide sufficient active sites and fast electron transmission channels. Under visible light irradiation, the Cu@Cu2O/N-GC-600 catalyst has the highest yields of CH4 and CO at 38.89 mu mol g(-1) and 27.78 mu mol g(-1), respectively. The excellent photocatalytic activity is attributed to the synergistic effects between the unique N-GC framework and core-shell Cu@Cu2O NPs, which accelerates the transfer of charge carriers and promotes the accumulation of photogenerated electrons on core-shell Cu@Cu2O. The results of this study may be beneficial for the design and synthesis of high-efficiency core-shell photocatalysts.
