“…Considering the abovementioned challenge, the design of materials that can effectively convert weak natural sunlight into thermal energy for VOC degradation without external heating is highly desirable. [ 159–161 ] Previously, using an optical concentrator, Li et al [ 89 ] demonstrated that a LaMn 1.3 O 3 catalyst achieved a toluene conversion and CO 2 yield of 98% and 70% under one sun irradiance with 94 mW cm −2 and maintained a CO 2 yield of 70%–85% under natural sun conditions. This study demonstrates a possible industrial application of ambient sunlight for VOC degradation over multicomposite catalysts.…”

“…The winter seasonal period was preferred due to the low ambient temperature and weak outdoor sunlight (<11 °C and 0.4 kWm −2 ). [ 159 ] As shown in Figure a, the Cu–CeO 2 MS was synthesized by dissolving Cu, CeO 2 , and PVP in an aqueous solution. This was subsequently sprayed in a hot environment at120 °C within 1 s to form dried microspheres which were subsequently annealed at 500 °C in air.…”

Harnessing Solar Energy Towards Synergistic Photothermal Catalytic Oxidation of Volatile Organic Compounds

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.
