A combination–decomposition method to synthesize two-dimensional metal sulfide–amine hybrid nanosheets: a highly efficient Fe-based water oxidation electrocatalyst

Abstract

Uniform FeS_1.4(Dmim)_0.5 (Dmim = 1-n-butyl-2,3-dimethylimidazolium cation) hybrid nanosheets were developed through an innovative combination–decomposition approach. More importantly, the obtained hybrid nanosheets demonstrate unprecedentedly high electrocatalytic activity, which represents the discovery of a novel, efficient Fe-based electrocatalyst and expands the scope of new types of electrolytic water oxidation.
