What are Some Key Catalytic Processes for Reducing Greenhouse Gases?
Carbon Capture and Utilization (CCU) Carbon capture and utilization involve capturing carbon dioxide (CO2) from industrial emissions and converting it into useful chemicals or fuels. Catalysts are essential in this process, particularly in the conversion of CO2 to methanol, a valuable chemical feedstock.
Hydrogenation Hydrogenation is a catalytic process that can convert CO2 into hydrocarbons. Using metal catalysts such as palladium or nickel, CO2 can be transformed into methane or other valuable hydrocarbons, thereby reducing its presence in the atmosphere.
Photocatalysis Photocatalysis involves using light to activate a catalyst, which then drives a chemical reaction. This method can be employed to reduce greenhouse gases by converting CO2 into fuels like hydrogen or methanol using solar energy and photocatalysts like titanium dioxide.
