利用混合阴离子半导体中的缺陷和特定的阴离子非化学计量比是光催化和光电化学水分解研究的前沿挑战。钙钛矿型氮氧化物中氧和氮缺陷之间的相互作用为优化这些材料的相稳定性、离子导电性和阴离子顺序创造了令人兴奋但又复杂的机会。本文重点介绍了氮氧化物半导体中的缺陷工程，如阴离子含量/非化学计量比、表面修饰、阳离子掺杂和各向异性层状结构的形成等在光催化和光电化学水分解方面的最新进展。讨论了值得进一步研究的途径。
Exploiting defects and specific anion non‐stoichiometry in mixed‐anion semiconductors is a challenge that remains at the forefront of photocatalytic and photoelectrochemical water splitting research. The interplay between of oxygen and nitrogen defects in perovskite oxynitrides specifically creates exciting, yet complex, opportunities for optimizing phase stability, ionic conduction and anion order in these materials. In this Minireview we highlight the recent advances in defect engineering in oxynitride semiconductors, such as anion content/non‐stoichiometry, surface modification, cation doping and formation of anisotropic layered structures, on photocatalytic and photoelectrochemical water splitting. Avenues warranting further investigation are discussed.
