Boosting the photocatalytic performance of Cu₂O for hydrogen generation by Au nanostructures and rGO nanosheets.

ABSTRACT: As a narrow band-gap semiconductor, cuprous oxide (Cu₂O) has a relatively high conduction band that can exhibit high driving force for the photocatalytic generation of hydrogen under visible light. Besides, its adjustable morphologies and abundant source also make it possible to be employed as a theoretically optimal photocatalyst. However, the low charge migration and poor stability commonly limit its practical application, and various strategies have been explored in previous studies. In this study, we have novelly utilized Au nanorod (NR) and nanobipyramid (NBP) nanocrystallites as well as rGO nanosheets to boost the photocatalytic activity of Cu₂O over hydrogen generation. The ternary rGO wrapped Au@Cu₂O with a yolk-shelled structure (y-Au@Cu₂
