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

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.
