Is the activated carbon in the filter specially treated to enhance its adsorption properties?

The activated carbon cabin filter in many activated carbon cabin filters has been specially treated to enhance its adsorption properties. These special treatments include:

Activation treatment: Activated carbon is activated, usually through high-temperature steam or chemical methods, to produce a large number of microporous structures on the surface, increasing its specific surface area and pore volume, thereby improving the adsorption performance. This treatment method can enhance the adsorption speed and adsorption capacity of activated carbon.

Chemical modification: Activated carbon undergoes chemical modification, such as acid-base treatment, oxidation treatment, etc., which can change its surface chemical properties, enhance the interaction with pollutants, and improve adsorption efficiency and selectivity.

Load addition: Add other adsorbents or catalysts, such as alumina, silica gel, etc., to the surface of activated carbon to form a composite adsorbent to improve adsorption efficiency and selectivity, while increasing the stability and regeneration of activated carbon.

Micropore filling: Filling or modifying the micropores of activated carbon, such as filling metal oxides, carbon nanotubes, etc., to regulate the pore structure and pore size distribution of activated carbon and improve the adsorption effect and anti-pollution performance.

Application of nanotechnology: Using nanotechnology to prepare activated carbon nanocomposites, such as nanoparticles, nanofibers, etc., can enhance the surface activity and adsorption performance of activated carbon.

These special treatments can improve the adsorption performance of activated carbon, making it more effective in removing pollutants in the air, including harmful gases, odors, volatile organic compounds, etc., in activated carbon cabin filters.
