Strategies to Develop Electrocatalytically Active Perovskite Oxide Nanosheets

Abstract

AbstractIn the research field of alternative energy, perovskite oxides remain one of the prominent classes of electrocatalysts because of their outstanding compositional and chemical versatility, tuneable catalytically active centers, and structural robustness leading to operational stability. However, their routine high‐temperature synthesis curbs the available active sites, and consequently, there is an ongoing urge to mend the perovskite oxides towards dimensionally reduced forms which can endow maximum surface‐active sites to accelerate the redox processes. Despite the burgeoning interests, research in this field barely began in the last decade. This review highlights some of the relevant literature findings, and rationalizes the limitations, and benefits of developing two‐dimensional (2D) nanostructures of electrocatalytically active perovskite oxides. Furthermore, the roadblocks of the current approaches for wide‐stretched adaptability and standing gaps to counter such bottlenecks are discussed.
