Tungsten-decorated MoP nanobelts for boosted hydrogen production
Abstract
To further improve the electrochemical catalytic performance of MoP for hydrogen generation, a tungsten decoration strategy is proposed in this work, and the effect of preparation temperature was also investigated. It is found that the decoration of W can significantly enhance the electron transfer ability and increase the amount of active sites, and the optimized catalyst can be obtained at 700 °C over the Mo-W-P-700 catalyst, which exhibits the best catalytic performance with a small Tafel slope of 53 mV dec ^-1 . This decoration strategy can be widely applied in other transition metal compounds to achieve further performance improvements.
