Pt nanoparticles-decorated molybdenum nitrides for efficient hydrogen evolution reaction.

ABSTRACT: Exploring low cost and high efficiency catalysts for hydrogen production from electrochemical water splitting is preferable and remains a significant challenge. As an alternative to Pt-based catalysts, molybdenum nitrides have attracted more attention for their hydrogen evolution reaction (HER). However, their performance is restricted due to the strong bonding of Mo-H. Herein, molybdenum nitrides with Pt-doping are fabricated to enhance the catalytic activity for HER in acidic solution. As expected, Pt (5 wt%)-MoN_x delivers a low overpotential of 47 mV at a current density of 10 mA cm^-2 with a high exchange current density (j₀ = 0.98 mA cm^-2). The superior performance is attributed to the modified electronic structure of Mo with Pt
