Iron-doped nickel sulfide@phosphate heterostructure nanosheets constructed from solvothermal P 2 S 5 and layered double hydroxides for electrocatalytic oxygen evolution

A heterogeneous nanostructured electrocatalyst Ni 0.9 Fe 0.1 S@NiFe(PO 4 ) x /NF has been prepared by a solvothermal reaction with NiFe-LDH/NF using P 2 S 5 as phosphorus and sulfur sources.
