Oxygen and phosphorus dual-doped MoS nanosheets (O,P-MoS) with porous structure and continuous conductive network are fabricated using a one-pot NaHPO-assisted hydrothermal approach. By simply changing the precursor solution, the chemical composition and resulting structure can be effectively controlled to obtain desired properties toward the hydrogen evolution reaction (HER). Thanks to the beneficial structure and strong synergistic effects between the incorporated oxygen and phosphorus, the optimal O,P-MoS exhibit superior electrocatalytic performances compared with those of oxygen single-doped MoS nanosheets (O-MoS). Specifically, a low HER onset overpotential of 150 mV with a small Tafel slope of 53 mV dec, excellent conductivity, and long-term durability are achieved by the structural engineering of MoS via O and P co-doping, making it an efficient HER electrocatalyst for water electrocatalysis. This work provides an alternative strategy to manipulate transition metal dichalcogenides as advanced materials for electrocatalytic and related energy applications.
