What is CO₂ Reduction?
CO₂ reduction refers to the process of converting carbon dioxide (CO₂) into valuable chemicals and fuels, thereby mitigating its negative impact on the environment. This process is crucial in addressing
climate change and reducing greenhouse gas emissions.
Why is Catalysis Important for CO₂ Reduction?
Catalysis plays a vital role in CO₂ reduction because it enhances the
rate of chemical reactions, making the conversion of CO₂ more efficient and economically viable. Catalysts lower the
activation energy required for reactions, enabling the use of milder conditions and reducing energy consumption.
