Enwrapping ZnIn2S4 on vacancy-rich Nb2O5 nanoplates for enhanced photocatalytic hydrogen evolution

Abstract

Effective separation of photogenerated charge carriers, enhanced reduction ability of conduction band electrons, and improved light harvesting ability are crucial for the significant improvement of photocatalytic H2 evolution activity over Z-scheme ZnIn2S4/v-Nb2O5 heterojunction.
