Indirect methanol synthesis from CO₂ through high-efficient dimethyl carbonate hydrogenation as a bridge below 100°C.

ABSTRACT: Developing an energy-efficient process to convert chemically inert CO₂ to methanol is of great significance in sustainable chemistry. Herein, we report an indirect pathway for methanol synthesis below 100 °C, utilizing CO₂-derived dimethyl carbonate (DMC) as a bridging molecule. By engineering oxygen vacancies in In₂O₃, we construct a Lewis acidic combination of In₅ sites and In₄…In_{4 ּ}pairs that efficiently activate H₂ and DMC, respectively. The spatial intimacy of In₅ and In₄…In₄ enables efficient transfer of generated *H, achieving a methanol generation rate of 31.6 mmol _ּg_cat^-1 h^-1 with >99.99% selectivity at 100 °C. Integra
