Identifying the high activity of the basal plane in 1T′-phase MoS2 towards electrochemical hydrogen evolution

Abstract

As a promising alternative hydrogen evolution catalyst, MoS₂ is well known for its active edge sites and the inert basal plane. Now, 1T′-MoS₂ crystals are prepared and processed into different electrochemical microcells based on individual MoS₂ nanosheets to reveal that the basal plane of 1T′-MoS₂ is highly catalytically active.
