et al.

Abstract: With the rapid development of novel energy conversion and storage technologies, there is a growing demand for enhanced performance in a wide range of electrocatalysts. Perovskite oxides (ABO3) have caused widespread concerns due to their excellent electrocatalytic properties, low cost, stable and reliable performance. In recent years, the research on anion O‐site doping of perovskite oxides has been a cynosure, which is considered as a promising route for enhancing performance. However, a systematic review sum… Show more

“…Aside from the commonly used method of doping cations into the B-site, the O-site in ABO 3 perovskite oxides is also adaptable, allowing partial substitution with halogen (F – , Cl – , and Br – ), and N 3– anions. , Notably, F, possessing a greater electronegativity in comparison to O, diminishes the bonding strength existing between metal ions and oxygen ions . This F substitution promotes oxygen vacancy formation, accelerates O 2– transport, and enhances the catalytic activity of perovskite oxides.…”

“…Perovskite oxides as a class of functional materials can be tailored to offer compositional flexibilities and exhibit rich structural properties. The A and B sites of perovskite can be partially substituted by other metal ions with comparable radii while retaining the crystal structure, thereby significantly altering the physical and chemical characteristics of perovskite by varying the component elements A and B. , As an emerging material, perovskite oxides have been extensively investigated for electrocatalysis in energy conversion. Our group has reported a general strategy utilizing perovskite oxides for nitrogen fixation reactions, revealing their great potential for electrocatalysis. , Despite considerable advances, the NO 3 RR performance remains inadequate and requires more improvement.…”
