Manipulating the electronic state of tungsten carbide using CoNi@N-doped carbon derived from a bimetallic MOF for enhanced electroreduction reactions

Porous transition metal carbides (TMC) with an electron-deficient surface were synthesized using MOFs as templates. The Co 1 Ni 1 @M x C@NC exhibited high HER activity with a low overpotential of 103 mV at 10 mA cm −2 due to the positively charged WC.
