Discovering superior basal plane active two-dimensional catalysts for hydrogen evolution

The emerging non-noble metal two-dimensional (2D) catalyst, such as MoS2, for the hydrogen evolution reaction (HER) is known to have an inert basal plane unless being converted to a metastable metallic phase or defect engineered. In order to take advantage of the majority of the material in such layered catalysts, fast screening of 2D catalysts with superior basal plane activity is imperative. A local electrochemical measurement method assisted...
