Human production and living processes emit excessive VOCs into the atmosphere, posing significant threats to both human health environment. The photothermal catalytic oxidation process is an organic combination of photocatalysis thermocatalysis. Utilizing degradation can achieve better activity at lower temperatures, resulting in more rapid thorough these compounds. Photothermal catalysis has been increasingly applied treatment atmospheric due its many advantages. A brief introduction on three modes presented. Depending main driving force reactions, they be categorized thermal-assisted (TAPC), photo-assisted thermal (PATC) photo-driven (PDTC). commonly used catalyst design methods reactor types for are also briefly introduced. This paper then focuses recent developments specific applications different their corresponding principles. Finally, problems challenges facing VOC through this method summarized, along with prospects future research.
