Abstract

Hierarchical transition-metal dichalcogenide nanosheets are constructed through a versatile strategy, where the thermal polymerization of melamine and subsequent decomposition of carbon nitride successively guide the horizontal and vertical growths of transition-metal chalcogenides. Abundant edges and high surface areas endow the hierarchical MoS2 and WS2 nanosheets with excellent electrocatalytic performance for hydrogen evolution, including low onset potentials and high current densities.

Keywords: electrocatalysts; hierarchical nanosheets; hydrogen evolution reaction; melamine; transition metal dichalcogenides.
