Review on the preparing,performance and applications of N-doped CeO2
Nitrogen doping has a significant impact on the physicochemical properties of CeO2.N-doped CeO2 exhibits excellent photocatalytic,thermal catalytic and electrochemical properties.Howev-er,there are relatively fewer studies on N-doped CeO2,and there is a lack of systematic summary and combing of its existing research results.In this review,the main methods of nitrogen doping in CeO2are summarized,the main effects and rules of nitrogen doping on its physical and chemical properties are discussed,and its main application fields are analyzed.It also provides some suggestions for the future study of N-doped CeO2,and hopes to play a certain guiding role for the study of N-doped CeO2 and CeO2-based functional materials.
