Free‐standing nanoporous metal phosphides are fabricated by a novel top‐down method, by selectively leaching less‐stable metal phases from rapidly solidified two‐phase metal–phosphorus alloys. The phosphide phases with relatively high electrochemical stability are left as the skeletons of nanoporous structures. The resultant nanoporous phosphides with tunable pore size and porosity show superior catalytic activities toward electrochemical hydrogen production.
