“…Numerous studies have dramatically proven the beneficial effect of surface modification. For instance, recent work by Li verified the enhancement of the oxygen evolution activity of a perovskite (La 0.8 Sr 0.2 ) 0.95 MnO 3-δ electrode by Co phase surface modification [132]. The surface modification of (La,Sr)MnO 3 with CoO(OH) or Co 3 O 4 by the hydrothermal method exhibits synergistically improved OER mass and specific activity over the individual phase.…”

Hydrogen is considered a promising clean energy vector with the features of high energy capacity and zero-carbon emission. Water splitting is an environment-friendly and effective route for producing high-purity hydrogen, which contains two important half-cell reactions, namely, the anodic oxygen evolution reaction (OER) and the cathodic hydrogen evolution reaction (HER). At the heart of water splitting is high-performance electrocatalysts that efficiently improve the rate and selectivity of key chemical reactions. Recently, perovskite oxides have emerged as promising candidates for efficient water splitting electrocatalysts owing to their low cost, high electrochemical stability, and compositional and structural flexibility allowing for the achievement of high intrinsic electrocatalytic activity. In this review, we summarize the present research progress in the design, development, and application of perovskite oxides for electrocatalytic water splitting. The emphasis is on the innovative synthesis strategies and a deeper understanding of structure–activity relationships through a combination of systematic characterization and theoretical research. Finally, the main challenges and prospects for the further development of more efficient electrocatalysts based on perovskite oxides are proposed. It is expected to give guidance for the development of novel non-noble metal catalysts in electrochemical water splitting.

“…[4][5][6][7][8] However, the oxygen evolution reaction (OER, 4OH À -O 2 + 2H 2 O + 4e À ) in alkaline water splitting is a very complex process involving four proton-coupled electrons transfer steps, O-H bond breaking and O-O bond formation, and thus has been widely recognized as the leading barrier for commercial hydrogen production using water-splitting devices. 5,[9][10][11] Accordingly, numerous low-cost and high-performance electrocatalysts based on metal oxides, [12][13][14] non-oxides, [15][16][17][18][19] and hydroxides 20,21 have been developed for OER. Nevertheless, the operation voltage of alkaline water splitting at the current density of 10 mA cm À2 is still larger than 1.4 V, which is mainly attributed to the sluggish anodic OER kinetics.…”

“…[4][5][6] During the electrochemical water splitting process, the oxygen evolution reaction (OER) determines the reaction rate due to its complex proton coupling step. [7][8][9] To date, noble metal electrocatalysts with state-of-theart catalytic activity, such as ruthenium and iridium oxides, have been developed as common reference catalysts for evaluating the OER performance of other catalysts. However, the scarcity, high cost, and long-term stability of the precious metals limit their large-scale application.…”
