英文摘要	Using transition metal disulfide (TMD) as a substitute for noble-metal-based catalysts is considered a promising strategy for achieving practical hydrogen production from water splitting. Herein, an earth-abundant, highly crystalline, bimetal disulfide nanoporous networks (Ni0.33Co0.67S2) was constructed via dealloying and low-temperature chemical vapor deposition (CVD) methods. As expected, the as-prepared Ni0.33Co0.67S2 can be served as an efficient, and robust electrocatalyst for HER, and exhibiting a lower overpotential (191.2 mV at 10 mA cm(-2)) and Tafel slope (93.64 mV dec(-1)) than that of NiS2 and CoS2 synthesized through the similar methods. Moreover, the potential increase is only 50 mV in 12 h of long-term durability test for Ni0.33Co0.67S2 catalyst. Further analysis shows the significantly improved performance of Ni0.33Co0.67S2 should be attributed to the enhanced charge transfer, as well as increased electrochemical active specific surface area. Therefore, the combination of versatile dealloying inheritance effect and CVD modification strategy could provide a promising channel for preparing practical HER catalyst.
