“Superaerophobic” NiCo Bimetallic Phosphides for High-Efficient Hydrogen Evolution Reaction Electrocatalysts

A “superaerophobic” NiCo bimetallic phosphides electrocatalyst has been fabricated by employing bimetal-organic frameworks as self-sacrificing templates. Only an overpotential of 205 mV can drive the HER current density to 800 mA cm-2, which is even superior to the Pt/C. This study provides a promising approach for the development of industrialized HER electrocatalysts.
