Electrocatalysis: Co‐doping Strategy for Developing Perovskite Oxides as Highly Efficient Electrocatalysts for Oxygen Evolution Reaction (Adv. Sci. 2/2016)

Perovskite oxides represent one category of efficient electrocatalysts for the oxygen evolution reaction (OER), a key reaction that enables conversion and storage of sustainable but intermittent energy sources. In article number 1500187, Z. Shao and co‐workers identify—through a synergistic co‐doping strategy—a series of cobalt‐based perovskite oxides that are both active and stable for OER in alkaline media. By tailoring the concentrations of less OER‐active dopants, tunable electrocatalytic activity is demonstrated.
