Abstract

The invention relates to a multifunctional high-efficiency integrated air pollution processing material and a preparation technology thereof, which belong to the technical field of normal temperature adsorption catalysis and air cleaning. The multifunctional high-efficiency integrated air pollution processing material is composed of an active carbon carrier with high specific surface area, a titania nano-tubes catalysis component, a nano non-precious metals catalysis component, a nano precious metals catalysis component and a high efficiency antibiosis component. The material has rapid removing and killing efficacy for common air pollutant such as benzene, toluene, VOCs, formaldehyde, CO, SO2, NO2 and bacteria, and can satisfy the requirement of removal of various indoor air pollutants with high efficiency under real environment.

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 continues to improve, and the rapid development of my country's real estate industry has brought about the vigorous development of the architectural decoration industry. Compared with for...
