Abstract The “Solar Sabatier” reaction has emerged as a promising sustainable method for the CO 2 hydrogenation. development of advanced metal‐support catalysts based on Strong Metal‐Support Interaction (SMSI) offers significant advantages in activation and regulation selectivity. Herein, novel composite Ni/CaTiO 3 catalyst consisting Ni Ni‐doped CaTiO is synthesized utilized methanation. A noteworthy finding that incorporation into matrix instrumental formation oxygen vacancies establishment SMSI between . enhanced resulting from surface‐doped atoms not only facilitated effective interface contact metallic surface but also significantly improved migration efficiency hydrogen reduced barrier methanation optimized rate‐limiting step, all which are advantageous Consequently, exhibited extraordinary performance, achieving conversion rate 87.77%, CH 4 generation 3.12 mol g −1 h , ≈100% selectivity under ambient pressure conditions. This investigation lays groundwork design highly active understanding mechanisms underlying SMSI.
