By the introduction of Fe element, a novel Fe-promoted MoP catalyst was proposed for the first time, which was prepared via a simple temperature-programmed reduction method. Benefitting from the promotion effect of Fe, the HER activity of the MoP catalyst is remarkably enhanced with smaller Tafel slope and much larger current density, which can be attributed to the reduced crystal size and smaller charge transfer resistances. However, it must be noted that the addition content of Fe must be accurately controlled, or the final HER activity will be deteriorated.
