A three-dimensional macroporous framework molybdenum disulfide–carbide heterojunction for highly efficient electrocatalytic hydrogen evolution at high current densities

Abstract

Herein, we report a facile solid-state synthesis strategy for the synthesis of a three-dimensional (3D) macroporous framework molybdenum disulfide–carbide (MoS₂–Mo₂C) heterojunction. The MoS₂–Mo₂C/Mo electrode exhibits excellent HER activity with low overpotentials of 56 and 446 mV at current densities of 10 and 1000 mA cm⁻², respectively, in alkaline electrolytes.
