| description | The hydrogenation of CO2 to methanol using H2 produced from renewable resources has been regarded as an effective way to mitigate CO2 emissions. Unfortunately, how to obtain both high activity and methanol selectivity is still a trade-off challenge for catalyst development. Herein, we synthesize Co-In-Zr ternary metal oxide precursors via a simple hydrothermal method for hydrogenation of CO2 to methanol. After reduction by H2, a part of Co and In cations could be reduced from the solid solution to generate CoIn alloy, simultaneously constructing oxygen vacancy rich environment on the catalyst surface. The increased concentration of surface oxygen vacancies can improve the adsorption and activation of CO2. Meanwhile, our findings show that the formed CoIn alloy significantly enhances the adsorption and dissociation of H2, thus accelerating successive hydroconversion of CO2 and intermediates to methanol. The synergy of CoIn alloy and oxygen vacancies significantly boosts both activity and methanol selectivity. Under the conditions of 300 °C and GHSV of 30,000 ml gcat-1 h-1, the catalyst with a Co: In: Zr molar ratio of 1: 2: 7 achieves the CO2 conversion of 10.2 %, the methanol selectivity of 81.5 %, and especially the methanol time-space yield up to 860 mg gcat-1 h-1, surpassing the majority of the state-of-the-art In-based catalysts. Moreover, the catalyst exhibits the excellent stability, maintaining the performance within 100 h. Our work provides insights into designing efficient none-noble-metal catalysts for CO2 hydrogenation reactions. |
