“…Determining the reasons why the BBSC series electrocatalysts possess excellent OER activity and stability is of great importance; it is also critical for the design of even better electrocatalysts. Based on previous studies, we know that the improved OER activity in alkaline solution can be attributed to the highly oxidative oxygen species (O 2 2− /O − ) formed on the surface of catalysts . Figure a shows the O 1s XPS spectra of BBSC0.1, BBSC0.2, and BBSC0.3, which can be deconvoluted into four characteristic peaks.…”

Simple disordered perovskite oxides have been intensively exploited as promising electrocatalysts for the oxygen evolution reaction (OER) towards their application in water splitting, reversible fuel cells, and rechargeable metal-air batteries. Here, the B-site cation-ordered double perovskites Ba Bi Sc Co O , with two types of cobalt local environments, are demonstrated to be superior electrocatalysts for OER in alkaline solution, demonstrating ultrahigh catalytic activity. In addition, no obvious performance degradation is observed for the Ba Bi Sc Co O sample after a continuous chronopotentiometry test. The critical role of the ordered [Co ] and [Sc , Bi , Co ] dual environments in improving OER activity is exhibited. These results indicate that B-site cation-ordered double perovskite oxides may represent a new class of promising electrocatalysts for the OER in sustainable energy storage and conversion systems.

“…Besides, the ECSA was also estimated from the gravimetric double layer capacitance as reported by Wu et al [44,45] At a scan rate of 20 mV s −1 , the calculated value of ECSA for SNCF-NR is ≈175 m 2 g −1 , which is much higher than that for SNCF (≈74 m 2 g −1 ). [53,54] XPS spectra of O 1s species (Figure 5f) and the corresponding deconvolution results (Table S5, Supporting Information) on the surface demonstrate a larger number of (O 2 2− /O − ) species for SNCF-NR. Rapid charge transfer is required for efficient OER and HER electrocatalysis.…”

The development of highly efficient and low‐cost electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is paramount for water splitting associated with the storage of clean and renewable energy. Here, this study reports its findings in the development of a nanostructured perovskite oxide as OER/HER bifunctional electrocatalyst for overall water splitting. Prepared by a facile electrospinning method, SrNb0.1Co0.7Fe0.2O3–δ perovskite nanorods (SNCF‐NRs) display excellent OER and HER activity and stability in an alkaline solution, benefiting from the catalytic nature of perovskites and unique structural features. More importantly, the SNCF‐NR delivers a current density of 10 mA cm−2 at a cell voltage of merely ≈1.68 V while maintaining remarkable durability when used as both anodic and cathodic catalysts in an alkaline water electrolyzer. The performance of this bifunctional perovskite material is among the best ever reported for overall water splitting, offering a cost‐effective alternative to noble metal based electrocatalysts.

“…However, this process requires large power consumption, and more often only produces perovskite nanomaterials with irregular shape, contaminants, or amorphous components. Additionally, researchers also succeeded in fabricating perovskite nanostructures using other approaches, such as combustion synthesis, flame spray synthesis, microwave‐assisted method, and others . For example, Liu et al used a one‐pot combustion process to synthesize a layered perovskite‐metal oxide nanohybrid, NiO–(La 0.613 Ca 0.387 ) 2 NiO 3.562 .…”

Perovskite oxides hold great promise as efficient electrocatalysts for various energy‐related applications owing to their low cost, flexible structure, and high intrinsic catalytic activity. However, conventional synthetic methods can only obtain perovskite catalysts with large particle sizes, small surface areas, and few morphological features, leading to limited catalytic activity and thus posing a major challenge toward real‐world applications. Reducing the size of bulk perovskites down to the nanosize represents an efficient way to improve the electrocatalytic performance. A comprehensive overview of recent progress in the nanostructuring of perovskites for catalyzing several key reactions in metal–air batteries, water splitting, and solid oxide fuel cells is provided. A range of synthetic protocols for making perovskite nanostructures are summarized, followed by an emphasis on how each method can be tailored to obtain high‐performing perovskite nanocatalysts. These recent advances highlight the enormous potential of nanosized perovskites for facilitating the electrocatalytic reactions. The remaining challenges and future directions are pointed out for the development of next‐generation perovskite‐based nanostructured catalysts.
