Abstract

Abstract Improving the separation of photogenerated carriers and suppressing the rapid complication of electron–hole pairs are essential ways to improve photocatalytic hydrogen production activity. The high recombination rate of the photogenerated carriers is an issue encountered when developing CdS as a promising photocatalytic material. This work allowed to accelerate the separation of photogenerated electrons and holes by loading monoclinic β‐AgVO 3 on hexagonal CdS nanorods to construct a one‐dimensional (1D)/1D p‐n heterojunction. The introduction of monoclinic β‐AgVO 3 with a narrow band gap effectively improves the light absorption of CdS, which is conducive to improving the use of visible light. The…
