Metal Oxides for Carbon Dioxide Capture and Conversion

Excessive use of fossil fuel raises the level of atmospheric CO 2 that put an environmental challenge, necessitating efficient CO 2 capture and conversion technologies. Metal oxides have gained popularity due to their remarkable thermal and chemical stability, tunable surface properties, and catalytic efficacy in CO 2 adsorption and related processes. This chapter analyzes the mechanisms of CO 2 capture using metal oxides, including physisorption, chemisorption, and carbonate synthesis. The book analyzes CO 2 conversion methodologies, including thermochemical reduction, electrochemical conversion, and photocatalytic processes, for the sustainable production of fuels and chemicals. Special attention is carried out on the role of nanostructured metal oxides in enhancing catalytic efficiency, selectivity, and recyclability. The chapter addresses significant challenges like energy efficiency, material degradation, and process scalability, while highlighting recent advancements and potential research directions in metal oxide-based CO 2 capture and conversion systems. So, metal oxides enable efficient and sustainable CO 2 capture and conversion through their stable, tunable, and catalytically active properties.
