Amorphous tungsten-doped nickel phosphide (a-WNP) microspheres with three-dimensional (3D) ravine-like nanostructures on the surface were successfully fabricated via a fast and facile grain-mediated electroless method. The resulting W-doped NixP exhibits an outstanding electrocatalytic activity for hydrogen evolution reaction with a low onset potential of -50 mV, overpotential of 110 mV at 20 mA cm(-2), and small Tafel slope of 39 mV dec(-1). The amorphous architecture and the doping of W are considered to be major contributions for the improvement of catalytic performance. The results in this paper might promote a new route to gain both amorphous and doped materials with special electrochemical properties for advanced catalysts and other devices.
