Synergistic effect between undercoordinated platinum atoms and defective nickel hydroxide on enhanced hydrogen evolution reaction in alkaline solution

The synergistic effect between undercoordinated Pt atoms and defective Ni(OH)2 nanosheets has an benefit on water dissociation in alkaline solution, in which the specific current density (mass current density) of concave cube (CNC) Pt-Mn/Ni(OH)2 for HER is 6.88 (4.80) times higher than that of nanocube Pt-Mn catalyst.237
