Hydrogen energy stands out as one of the most promising alternative energy sources due to its cleanliness and renewability.Electrocatalytic water splitting offers a sustainable pathway for hydrogen production.However,the kinetic rate of the hydrogen evolution reaction(HER)is sluggish,emphasizing the critical need for stable and highly active electrocatalysts to facilitate HER and enhance reaction efficiency.Transition metal-based catalysts have garnered attention for their favorable catalytic activity in electrochemical hydrogen evolution in alkaline electrolytes.In this investigation,flower-like nanorods of MoS2 were directly synthesized in situ on a nickel foam substrate,followed by the formation of MoP/MoS2-nickel foam(NF)heterostructures through high-temperature phosphating in a tube furnace environment.The findings reveal that MoP/MoS2-NF-450 exhibits outstanding electrocatalytic performance in an alkaline milieu,demonstrating a low overpotential(90 mV)and remarkable durability at a current density of 10 mA/cm2.Comprehensive analysis indicates that the introduction of phosphorus(P)atoms enhances the synergistic effect with MoS2,while the distinctive flower-like nanorod structure of MoS2 exposes more active sites.Moreover,the interface between the MoP/MoS2 heterostructure and NF facilitates electron transfer during hydrogen evolution,thereby enhancing electrocatalytic performance.The design and synthesis of such catalysts offer a valuable approach for the development of high-performance hydrogen evolution electrocatalysts.
