摘要

•S atoms are doped into N-rich Mo5N6 through controlled topochemical substitution.•The S dopants induce the electron redistribution of Mo5N6.•DFT simulations reveal the optimized ΔGH* value of −0.06 eV on the basal planes.•S-Mo5N6 can achieve 10 mA cm−2 with an overpotential of 56 mV and a Tafel slope of 37.9 mV dec-1.
