摘要：

This study presents a method for preparing tungsten-based electrocatalysts using a steam assisted carburization strategy. The WC/W2C base with eutectoid-structured was prepared by a customized carburization strategy, and the WS2/WO3 heterojunction was successfully introduced by adjusting the steam content. Thanks to the synergies and electronic effects between the WS2/WO3 interface and the WC/W2C base, the prepared catalyst exhibited excellent HER activity, with an overpotential of only 89 mV at a current density of 10 mA/cm2, and the stability could be maintained for more than 60 h. This study not only discusses the synthesis mechanism of WS2/ WO3-WC/W2C, but also provides a new idea for the study of high-performance tungsten-based HER catalysts, challenging the dominance of commercial Pt/C catalysts.
