摘要：

Developing non-precious metal catalyst with high activity, good stability and low cost for electrocatalytic hydrogen evolution reaction (HER) is critical for hydrogen product from water splitting. Here, we proposed a facile and effective approach to in situ synthesize highly efficient and ultrastable iron phosphide hybrids anchored inside a hollow N-P codoped carbon derived from MIL-101-NH2-Fe-P (not only acting as multifunctional precursor but also nanoscale confined space during pyrolysis) via one-step method for HER. The newly developed FexP@NPC catalyst exhibits high electrocatalytic activity and shows a nearly constant voltage with only less 0.1% increase at 10 mA cm(-2) after 90 h in full water splitting cell with high Faradaic efficiency of near 100% and keep very similar level even after shelving 10 days.
