Abstract

The invention relates to a preparation method of a composite adsorption material with MAR and MIL-53 (Al) combined. The composite adsorption material is a carrier growing by adopting porous resin (MAR) as crystals, a metal organic frame material is formed by organic ligands in the porous resin, and the outer diameter of particles of the composite material ranges from 3 mm to 6 mm. A solvent thermal method is adopted for preparing the composite adsorption material with MAR and MIL-53 (Al) combined, the composite material solves the problem that a single MIL-53 (Al) material can only form powder and cannot be used for air filtering and the problem that the porous resin is too large in aperture and small in specific area, and the existing technical bottleneck of filtering of ultralow-concentration micromolecular gaseous pollutants in actual application can be broken through.

Description

technical field

[0001] The invention belongs to the field of preparation of air pollutant purification materials, and in particular relates to a composite adsorption material combined with MAR and MIL-53 (Al) and a preparation method thereof. Background technique

[0002] At present, air pollution has become a topic of increasing concern, from indoor ambient air to urban atmospheric environment, to global air pollution. According to data released by the World Health Organization, in 2012, the number of deaths from various diseases caused by air pollution in the world was about 7 million. For a healthy and high-quality living environment, it is necessary to improve and invent new purification materials and equipment. Especially for some polluting gases with small particle size (0.1-0.9nm), such as formaldehyde (0.414nm), benzene (0.58nm), methane (0.414nm), etc., the existing porous materials (activated carbon, macroporous resin ), the adsorption effect of these small molec...
