Abstract Since the excessive exploitation of fossil fuels will cause wars for oil, developing sustainable and eco‐friendly energy resources to solve crisis realize carbon‐neutrality goal has been a hot issue. Water electrolysis acknowledged as promising technology hydrogen (H 2 )/oxygen (O ) evolution reaction (HER/OER) since overall water splitting rates can be well controlled by applying appropriate electrode voltage. Whereas sluggish electrochemical reactions kinetics on both cathode anode have greatly restricted conversion efficiency. Thus, highly active electrocatalysts reduce overpotentials required electrolytic HER/OER is great significance in increasing utilization electrical power lowering production costs. ABO 3 ‐structured perovskite‐oxides based possess merits low cost, high structural stability, lattice compatibility, thus they attracted intense research attention recent decays. To inspire theoretical experimental researchers design novel perovskite‐oxide efficient HER/OER, fundamental mechanisms, effects synthetic methods material morphologies, recently reported effective tuning strategies enhancing electrocatalytic activities existing fully discussed this review.
