Ce-metal organic framework and reduced graphene oxide co-enhanced the H2 evolution ability of CdS/single crystal ZnO nanorod photocatalyst

Abstract

To enhance the photocatalytic H2 production capacity of reduced graphene oxide/CdS/single crystal ZnO nanorod (RGOCZ) ternary material, Ce-organic framework [UiO66-(Ce)]/rGO/CdS/single crystal ZnO nanorod (URGOCZ) quaternary material was prepared by microwave-assisted co-precipitation method, and the influence of UiO66-(Ce) content on the photocatalytic performance of quaternary material was analyzed. The experimental study shows that RGOCZ ternary material is anchored in the surface of the UiO66-(Ce), and the photocatalytic H2 evolution capacity of RGOCZ ternary material is enhanced by UiO66-(Ce) significantly. When 15 mL UiO66-(Ce) solution (0.4 g/L) is added, the photocatalytic H2 evolution efficiency of 15URGOCZ quaternary material reaches 10.55 mmol g−1 h−1.
