Abstract
Highly efficient, cost-effective, and stable non-noble metal electrocatalysts are desirable for cathodic hydrogen evolution reaction (HER). Herein, crystal defects were created in MoS2 with the substitution of P dopants in order to catalyze HER effectively. Performance of MoS2 in electrocatalytic HER is poor in terms of high onset potential and overpotential due to poor intrinsic conductivity. The issue regarding conductivity and reducing onset potential as well as overpotential can be addressed by low electronegative element "P" substitution into the S sites of MoS2 and incorporating additionally dual heteroatom atom (nitrogen, sulfur) doped reduced graphene oxide (rGO).
