Carbon dioxide (

CO2) methanation, also known as the Sabatier reaction, is a promising strategy for mitigating greenhouse

gas emissions while enabling the storage of renewable hydrogen in the form of methane. However, achieving high catalytic

activity, selectivity, and long-term stability under industrially relevant conditions requires the development of catalysts with

tailored structural and functional properties. Conventional catalysts based on Ni, Ru, and Rh have demonstrated considerable

performance in CO2

methanation. Nevertheless, challenges associated with high-temperature catalysis such as thermal

degradation, carbon deposition (coking), and the high cost of noble metals still remain. To address these issues, oxide-type

materials have attracted increasing attention due to their multifunctional roles not only as catalyst supports but also as active

materials in the catalytic process. Simple oxides such as Al2O3,

SiO2,

CeO2,

and ZrO2,

as well as more structurally complex

oxides such as perovskites (e.g., LaNiO3,

SrTiO3)

and spinels (e.g., MgAl2O4),

can significantly influence metal dispersion,

reducibility, and metal–support interaction strength. As a result, these characteristics critically affect both catalytic

performance and durability of CO2

methanation. Moreover, many oxides actively participate in the reaction mechanism by

facilitating oxygen vacancy formation, hydrogen spillover, and dynamic redox behavior, making them essential components

in the design of next-generation CO2

methanation catalysts. This review summarizes recent progress in oxide-type materials

for catalytic CO2

methanation and highlights material design strategies aimed at developing catalysts with high activity,

selectivity, and durability.
