As typical air pollutants, CO, CH4, and volatile organic compounds (VOCs) have received great attention due to their negative impact on the environment and human health. Heterogeneous catalysts are widely used in the catalytic removal of exhaust emission from industrial and automobile sources but still suffer from deactivation because of various factors. The development of a catalyst with excellent catalytic stability is highly desired. We herein summarized the recent progress for enhancing the catalytic stability of catalysts and tried to obtain an in-depth understanding of the long-term durability, resistance to sinter, and tolerance for multi-impurities. Finally, the current challenges and future perspectives for developing stable and highly efficient catalysts in the fields of synergistic catalytic removal of pollutants or resource utilization of VOCs via the selective catalytic oxidation are proposed.

Volatile organic compounds (VOCs) are prominent air pollutants, hazardous to human health and the environment. Sunlight is a sustainable energy source capable of meeting the demands for heterogeneous catalysis. Photothermal catalysis has emerged as an energy‐efficient technology for VOCs oxidation by merging the advantages of thermochemistry and photocatalysis. This review examines the advantages of the photothermal catalytic system, such as the absorption and conversion of solar light, accelerated reaction rates, and improved product selectivity. The photothermal catalytic system is clearly categorized according to the significant contributions of light and thermal energy to the reaction. As a result of the direct conversion of photons into thermal energy to surpass the light‐off temperature and drive the catalytic reaction, an ample discussion of light‐induced thermal catalytic processes is presented. Furthermore, the participation of the localized surface plasmon resonance effect and oxygen vacancies in the surface reaction under irradiation and thermal energy are spotlighted. A comprehensive discussion is provided for the various photothermal active nanostructures. The underlying superior resistance mechanism to water vapour and coke formation as well as high oxygen concentrations in photothermal catalytic system are emphatically highlighted. Finally, current research trends and prospects are discussed.

The volatile organic compounds (VOCs) from cooking oil fumes are very complex and do harm to humans and the environment. Herein, we develop the high-efficiency and energy-saving synergistic photothermocatalytic oxidation approach to eliminate the mixture of heptane and hexanal, the representative VOCs with high concentrations in cooking oil fumes. The Pt/ CeO 2 /TiO 2 catalyst with nanosized Pt particles was prepared by the simple hydrothermal and impregnation methods, and the physicochemical properties of the catalyst were measured using numerous techniques. The Pt/CeO 2 /TiO 2 catalyst eliminated the VOC mixture at low light intensity (100 mW cm −2 ) and low temperature (200 °C). In addition, it showed 25 h of catalytic stability and water resistance (water concentration up to 20 vol %) at 140 or 190 °C. It is concluded that O 2 picked up the electrons from Pt to generate the • O 2 − species, which were transformed to the O 2 2− and O − species after the rise in temperature. In the presence of water, the • OH species induced by light irradiation on the catalyst surface and the • OOH species formed via the thermal reaction were both supplementary oxygen species for VOC oxidation. The synergistic interaction of photo-and thermocatalysis was generated by the reactive oxygen species.
