Volatile organic compounds are a kind of important indoor and outdoor air pollutants. In recent years, more and more attention has been paid to the ways of volatile organic compound elimination because of its potential long‐term effects on human health. Among the various available methods for volatile organic compound elimination, the catalytic combustion is the most attractive method due to its high efficiency, low cost, simple operation, and easy scale‐up. Perovskite oxides, as a large family of metal oxides with their A‐site mainly of lanthanide element and/or alkaline earth metal element and B‐site of transition metal element, have been extensively investigated as active and stable catalysts for volatile organic compound removal reactions due to their abundant compositional elements, high thermal/chemical stability, and compositional/structural flexibility. The catalytic performance of perovskite oxides is strongly depended on its material composition, morphology, and surface/bulk properties, while the doping, tailored synthesis route, and composite construction may have a significant effect on the bulk (oxygen vacancy concentration, lattice structure), surface (oxygen species, defect) properties, and particulate morphology, consequently the catalytic activity and stability for volatile organic compound removal. Herein, a comprehensive review about the recent advances in perovskite oxides for volatile organic compound elimination reactions based on catalytic combustion is presented from different aspects with a special emphasis on the material design strategies, such as compositional tuning, morphology control, nanostructure building, hybrid construction, and surface modification. At last, some perspectives are presented on the development and design of perovskite oxide‐based catalysts for volatile organic compound removal applications by highlighgting the critical issues and challenges.
