Abstract

The invention mainly relates to a fullerene photocatalyst composite material composition. The composite material composition can degrade formaldehyde, TVOC and other air pollutants under visible light, and is low in cost, simple in process route, excellent in air pollutant degradation performance and free of secondary pollution. The fullerene photocatalyst composite material composition disclosed by the invention has good photochemical stability, and the catalytic performance of the material is not obviously changed after the fullerene photocatalyst composite material composition is recycled.

Description

technical field [0001] The disclosure relates to the field of photocatalysis, and further relates to the preparation and application of the fullerene photocatalyst composite material composition. Background technique [0002] With the improvement of people's living standards, the number of house decorations is increasing day by day, and the organic gases such as formaldehyde, benzene, and ammonia released from materials such as coatings, paints, and foam fillers used in these decorations have caused serious pollution of indoor air. , can cause great harm to the human body. The most common of these is formaldehyde pollution, which often seriously exceeds the standard. Formaldehyde is a recognized potential carcinogen in the world, and low concentration of formaldehyde can cause chronic respiratory diseases, leukemia, asthma, etc. Therefore, the effective removal of formaldehyde and other harmful gases has become an important part of environmental protection today and should...
