摘　　要：Cerium dioxide(CeO_(2))is a significant rare earth oxide with the merits of rich oxygen defects,specific4f^(1)5d^(1)orbitals,and superior oxygen storage-release capacity in Ce^(4+)/Ce^(3+)reversibility pairs,and has been widely investigated as an active photocatalytic material for air pollution remediation.To enhance the photocatalytic efficiency of CeO_(2),recent developments of numerous modification strategies have been employed to broaden the light absorption range and reduce the recombination rate of electron-hole pairs.This review summarizes the fabrication of modified CeO_(2)catalysts,including metal or nonmetal doping,heterostructure construction and oxygen vacancy manufacturing,to provide insight into how those advanced techniques improve the photocatalytic activity.Moreover,this work provides a detailed discussion on the usage of modified CeO_(2)in the fields of air pollution control,including nitrogen oxides removal,volatile organic compounds elimination and the purification of carbon dioxide.Finally,the potential future development and further research on the modification of CeO_(2)has been identified.
