Addressing the critical challenge of atmospheric pollution, from both stationary and mobile sources, necessitates the development of highly efficient catalytic technologies. Although traditional metal oxides have been utilized in practical applications, the increasing requirements for structural flexibility, thermochemical stability, and resistance to extreme environments have stimulated the development of perovskite oxides. This review systematically consolidates the current understanding of perovskite materials, focusing on the pivotal role of electronic descriptors in predicting catalytic activity and guiding their rational design. A detailed overview of perovskite oxide design strategies sets the stage for understanding their consequent structural and catalytic properties. Further, the mechanistic insights into their performance across various pollution abatement reactions involving oxidation reactions, reduction reactions, and synergistic reactions are deeply understood. This work highlights the transformative potential of advanced operando characterization techniques, probing the dynamic evolution of active sites and surface intermediates under working conditions. Collectively, this review offers a blueprint for the future development of perovskite‐based catalysts, establishing a mechanistic paradigm applicable to a broader range of oxide materials.
