Carbon dioxide adsorbents are materials that have the ability to selectively capture and hold carbon dioxide molecules. These adsorbents can be used in various applications, such as carbon capture and storage, air purification, and gas separation.
There are many different types of carbon dioxide adsorbents, including zeolites, activated carbon, metal-organic frameworks (MOFs), and porous polymers. Each of these materials has its own unique properties and advantages.
Zeolites are crystalline materials that have a regular, porous structure. They have been extensively studied for their ability to adsorb carbon dioxide and are commonly used in industrial processes.
Activated carbon is a highly porous material that is widely used for gas purification and separation. It can be modified to increase its carbon dioxide adsorption capacity.
MOFs are a relatively new class of materials that are composed of metal ions or clusters linked by organic ligands. They have large surface areas and can be tailored to have specific properties, including high carbon dioxide adsorption capacity.
Porous polymers are another class of materials that have been studied for their carbon dioxide adsorption properties. They are lightweight and have high surface areas, making them attractive for applications such as gas separation.
