Engineering interfacial charge-transfer by phase transition realizing enhanced photocatalytic hydrogen evolution activity

Abstract

Thin, planar nanojunctions between layered 2H/1T-MoS₂ and graphitic C₃N₄ (g-C₃N₄) were fabricated and 1T phase nanojunctions allowed faster photogenerated electrons across the junction interfaces to facilitate hydrogen evolution. This research represents a proof of concept for the rational fabrication of thin 1T phase interfacial junctions and the importance of the 1T phase for further improving the HER perfomance.
