ABSTRACT
FeNi oxides/hydroxides are the best performing catalysts for oxidizing water at basic pH. Consequently, their improvement is the cornerstone to develop more efficient artificial photosynthetic systems. During the last 5â years different reports have demonstrated an enhancement of their activity by engineering their structures via: (1)â modulation of the number of oxygen, iron and nickel vacancies; (2)â single atoms (SAs) doping with metals such as Au, Ir, Ru and Pt; and (3)â modification of their surface using organic ligands. All these strategies have led to more active and stable electrocatalysts for oxygen evolution rection (OER). In this Concept, we critically analyze these strategies using the most relevant examples.
