Currently, inhalable particulate matter has become an important source of harm to air quality, and volatile organic compounds, referred to as VOCs, are a major source of inhalable particulate matter. Currently, VOCs mainly come from industrial production. In various occasions where organic solvents are used, such as painting, printing, metal degreasing and degreasing, and adhesives, volatile organic compounds are constantly polluting the air. In order to maintain the air quality in the environment, catalytic oxidation and other methods are usually used to remove volatile organic compounds.
