Metal oxides have emerged as highly versatile and chemically tunable materials for addressing the global challenge of rising CO₂ emissions, which reached a record 37.8 Gt in 2024. This chapter reviews both established and emerging carbon dioxide removal (CDR) technologies, positioning metal oxides as central materials across multiple strategies including direct air capture, mineralization, enhanced weathering, and photocatalytic CO₂ reduction. The distinct chemical properties of alkaline earth oxides (CaO, MgO), transition metal oxides (TiO₂, Fe₂O₃, MnOₓ, CuO), and mixed metal oxide perovskites are examined in terms of their CO₂ adsorption mechanisms, redox activity, thermal stability, and bandgap tunability.
