[0002] Air pollution is one of the major environmental issues facing my country. Especially this year, with the development of petrochemical, chemical and coating industries, the emission of volatile organic compounds (VOCs) has increased significantly.

[0003] VOCs are not only important precursor pollutants of ozone, but also the main cause of the formation of gaseous pollutants in haze. However, they have only received attention in recent years. VOCs are complex and usually exist in multiple components at the same time. Photocatalytic technology has the advantages of deep reaction at room temperature, direct use of solar energy to drive the reaction, low cost, and environmental friendliness, making it an ideal technology for environmental pollution control.
