Common porous materials used for gas purification include activated carbon, zeolites, and metal-organic frameworks (MOFs), which all have a high surface area with well-defined pore structures allowing for selective adsorption of specific gas molecules based on size and chemical properties; making them suitable for filtering and separating various gases in a purification process
Activated carbon
A widely used porous material with a high surface area, often employed for removing organic vapors and pollutants from gas streams.
Zeolites
Crystalline structures with uniform pore sizes, allowing for selective adsorption of specific gas molecules based on their size and shape.
Metal-Organic Frameworks (MOFs):
A newer class of porous materials with highly customizable pore structures by tailoring the metal ions and organic linkers, enabling precise gas separation capabilities.
Other porous materials used for gas purification:
Silica gel
Used for moisture removal from gas streams
Polymer resins
Can be designed for specific gas adsorption based on their functional groups
Covalent organic frameworks (COFs)
Another type of highly porous material with potential for gas separation applications
