AbstractSeeking more economical alternative electrocatalysts without sacrificing much in performance to replace precious metal Pt is one of the major research topics in hydrogen evolution reactions (HER). Tungsten disulfide (WS ) has been recognized as a promising substitute for Pt owing to its high efficiency and low-cost. Since most existing works adopt solution-synthesized WS crystallites for HER, direct growth of WS layered materials on conducting substrates should offer new opportunities. The growth of WS by the thermolysis of ammonium tetrathiotungstate (NH ) WS was examined under various gaseous environments. Structural analysis and electrochemical studies show that the H S environment leads to the WS catalysts with superior HER performance with an extremely low overpotential (η10 = 184 mV). 2 2 2 2 4 2 4 2 2
