Self-supported ternary Ni-Fe-P nanosheets derived from metal-organic frameworks as efficient overall water splitting electrocatalysts

Self-supported ternary Ni-Fe-P nanosheets were synthesized via the in-situ chemical etching of Ni foam to form metal-organic framework and subsequently phosphating treatment. Benefiting from the unique porous structure featuring with interconnected nanosheets, Fe incorporation, and the high conductivity of nickel foam, the resulting Ni-Fe-P/NF exhibits superior overall electrochemical water splitting performances when used as self-supported and binder-free working electrode.302
