Gas adsorbent
The gas adsorbent is montmorillonite clay modified by purifying sodium, acidification, column brace and organic. And the purity, cation exchangeability and quantity, adsorption, interlayer structure and interlayer environment of montmorillonite are significantly improved after modification.
By sodification, the internal specific surface area and charge of montmorillonite can be improved, and its adsorption performance can be enhanced.
Through acidification modification, the pore channel and void structure of montmorillonite were improved, the layer spacing was changed, and the microporous network structure was added, and the contact between gas and montmorillonite surface was increased, and the adsorption and chemical properties were improved. At the same time, acidification increases the acidity of the surface of montmorillonite and increases its adsorption capacity. For example, the adsorption of formaldehyde is because the surface of montmorillonite after acid treatment is rich in protons, and it is easy to form hydrogen bonds with oxygen atoms in formaldehyde steam, resulting in adsorption.
Through organic modification, the pore structure and the active site of the montmorillonite surface were improved. For example, for the adsorption and capture of CO2, the base active site can be increased.
The use of modified montmorillonite as the carrier and nanomaterials to prepare composite photocatalysts through column braces can have the advantages of both adsorption and photocatalysis.
