▎ 摘　　要

The development of an artificial model of photoinduced hydrogen production system requires efficient, long-term stability and cost-competitive photocatalysts to store solar energy in chemical bonds. However, the existing photocatalysts still suffer from the high cost, high recombination rate of photoexcited electron hole pairs, and poor photostability. Herein, we demonstrate the synthesis of a p-type CuO/n-type CeO2 heterojunction in situ grown on graphene via a hypha assistance process. Amazingly, optical and photoelectrochemical measurements show the superiority of this hierarchically biomorphic structure. The observed H-2 evolution rate of the CeO2-CuO quantum dots/graphene has reached 2481 mu mol.h(-1).g(-1) and remains unchanged in four hydrogen production cycles. Considering the convenience of microbial culture, this heterostructure system has great potential as a photocatalyst for solar-fuel conversion.
