Description

technical field [0001] A multifunctional and efficient integrated air pollution treatment material formula and its preparation process relate to nanometer multifunctional composite modified carbon-based materials and belong to the technical field of normal temperature adsorption catalysis and air purification. Background technique [0002] Modern people spend at least 70% of their time indoors, while the urban population spends more than 90% of their time indoors, especially infants and the elderly, weak and disabled. However, the concentration of indoor air pollutants is generally 2 to 5 times that of outdoor pollutants, and in some cases is tens or even hundreds of times that of outdoor pollutants. With the rapid development of social economy, modern people's pursuit of high-quality life is constantly improving, and the rapid development of my country's real estate industry has brought about the vigorous development of the architectural decoration industry. Compared with ...
