Volatile organic pollutants (VOCs) are important prebodies for the formation of ozone and PM2.5, and it is of great significance to study VOCs treatment technology. Catalytic oxidation technology is to break down VOCs oxidation into non-toxic CO2 and H2O under the action of catalysts, which is one of the most effective treatment methods. This paper summarizes the research progress of VOCs catalytic oxidation technology at home and abroad, the high energy consumption of traditional thermal catalytic oxidation technology and the low efficiency of photocatalytic purification technology, and summarizes the VOCs composition, its action structure and engineering application of different photothermal catalysts, and looks forward to the future development direction of VOCs photothermal catalytic oxidation technology.
