“…The OER is a multistep reaction pathway, including the absorption of reactive molecules, transformation of intermediates, and dissociation of product, which is closely associated to the strength of the B–O bond and the coordination structure around the B-site metal in the perovskite. − Based on this theory, an unsaturated coordination environment for B–O bonds or B-position atoms is created by introducing anion or cation vacancies into the structure of the perovskite. Ramezanipour et al reported an oxygen-deficient Sr 2 Fe 2 O 6‑δ perovskite, and its intrinsic OER activity is better than those of BSCF and RuO 2 .…”

Alkaline water splitting is a technique utilizing renewable resource-derived electricity to generate hydrogen with high purity. The oxygen evolution reaction (OER) with sluggish dynamics is the crucial half-reaction toward electrocatalytic water splitting, which needs a non-noble metal catalyst with high performance to make the reaction process be more energy-efficient and economical. Perovskite, as a kind of price moderate, compositional adjustable, structurally stable, and highly active material, has been widely used as the catalyst for the OER under alkaline conditions. In this review, we systematically expound the OERrelated catalytic mechanism, provide the evaluative criteria of catalytic performance, and then summarize the corresponding measurement methods of catalysts for the alkaline OER. Furthermore, our emphasis is given to the synthetic methods, the activity descriptors, and the performance optimization strategies of perovskite-based catalysts. Finally, we present a number of future directions on the development of more highly efficient perovskite-based catalysts for the alkaline OER.
