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