摘要

As a visible-light response photocatalyst,BiVO4 is widely used in photocatalytic oxygen evolution.In this study,a novel BiVO4-Bi6O6(OH)3(NO3)3(BBN)heterostructure fabricates via a simple one-pot hydrothermal approach is certified to effectively restrain the recombination of carriers by efficient spa-tial charge separation.By employing BBN as a reductive-function photocatalyst,a solid-state Z-scheme is constructed to improve the photo-redox capacity of BiVO4 and hydrogen production is realized in the BiVO4-BBN heterostructure for the first time.The solid-state Z-scheme introduced in the BiVO4-BBN ensures the photoexcited carriers with the powerful redox capacity to participate in the photocatalytic reaction.
