What are the Types of CO₂ Capture Methods Involving Catalysis?
There are several methods of CO₂ capture that employ catalysis:
Absorption: This method involves the use of liquid solvents that react with CO₂ to form a compound. Catalysts can improve the reaction kinetics and regeneration of the solvents. Adsorption: In this approach, solid materials known as adsorbents capture CO₂ on their surface. Catalysts can enhance the adsorption capacity and selectivity of these materials. Membrane Separation: Membranes can be coated with catalytic materials to improve the selectivity and permeability for CO₂. Conversion: CO₂ can be converted into useful chemicals or fuels. Catalysts are crucial in processes like methanation, where CO₂ is converted into methane, or in electrochemical reduction to convert CO₂ into carbon monoxide or other hydrocarbons.
