从晶体结构、制备方法和应用三方面综述了钙钛矿氮氧化物研究的新进展.钙钛矿氮氧化物有立方、四方和正交三大晶系,主要制备方法包括溶胶凝胶联合氨解法和高温固相反应联合氨解法,主要应用于光催化、染料颜料、磁阻材料和净化剂等领域.此外,还展望了钙钛矿氮氧化物的制备和应用前景.%Recent development of perovskite oxynitrides is reviewed from the aspects of crystal structure, preparation methods and application. The perovskite oxynitrides have cubic, tetragonal and orthorhombic crystallization system. Sol-gel with ammonolysis process and high temperature solid reaction ammonolysis method are the main methods that are employed to synthesize perovskite oxynitrides, which are widely used in the areas of photocatalysis, dye and paint, magnetoresistance materials, scavenger, etc. Moreover, the preparation and application prospects of perovskite oxynitrides are discussed.
