Enhanced Electron Transfer over Active Edge Sites in Layered MoS2 on Graphene Sheets for Efficient Photosensitized Hydrogen Evolution

It is highly desirable to develop highly active and cheaper co-catalysts. In this paper, layered MoS2 nanocatalyst was deposited on graphene sheets, and showed high performances for activity of photocatalytic hydrogen evolution reaction(HER). The nanohybrid catalyst’s activity is dependent on the chemical and electronic coupling interactions between MoS2 and graphene.
