Description

technical field [0001] The invention relates to the field of new materials, in particular to a high-performance adsorption catalytic material. Background technique [0002] At present, our country has entered a period of high incidence of environmental pollution accidents. The severity of environmental pollution has begun to affect people's production and life, and has gradually become an obstacle to the sustainable development of our country. Among the environmental pollution problems, the pollution of volatile organic substances is particularly serious. Effectively controlling the release of organic volatiles is the best way to protect the ecological environment, a necessary means for the healthy development of my country's manufacturing industry, and a responsibility entrusted to us by history. [0003] After decoration, the content of volatile organic compounds in the indoor air generally exceeds the standard. And it is very complicated in terms of its composition, so...
