Co‐doping Strategy for Developing Perovskite Oxides as Highly Efficient Electrocatalysts for Oxygen Evolution Reaction

A synergistic co‐doping strategy is proposed to identify a series of BaCo(0.9–x)Fe(x)Sn(0.1)O(3–δ) perovskites with tunable electrocatalytic activity for the oxygen evolution reaction (OER). Simply through tailoring the relative concentrations of less OER‐active tin and iron dopants, a cubic perovsk...

description A synergistic co‐doping strategy is proposed to identify a series of BaCo(0.9–x)Fe(x)Sn(0.1)O(3–δ) perovskites with tunable electrocatalytic activity for the oxygen evolution reaction (OER). Simply through tailoring the relative concentrations of less OER‐active tin and iron dopants, a cubic perovskite structure (BaCo(0.7)Fe(0.2)Sn(0.1)O(3–δ)) is stabilized, showing intrinsic OER activity >1 order of magnitude larger than IrO(2) and a Tafel slope of 69 mV dec(−1).
