Ultrastable hydrogen evolution electrocatalyst derived from phosphide postmodified metal-organic frameworks

A facile and effective approach was proposed to in situ synthesize highly efficient non-precious iron phosphide hybrids anchored in an N-P codoped hollow carbon derived from MIL-101-NH2-Fe-P via one-step method for HER. The newly developed FexP@NPC catalyst exhibits high electrocatalytic activity and extraordinary stability in acidic media in full water splitting cell with high Faradaic efficiency of near 100%.384
