Abstract
The selective hydrogenation of CO2 to methanol by renewable hydrogen source represents an attractive route for CO2 recycling and carbon neutral. Stable catalysts with high activity and methanol selectivity are being hotly pursued, and current debates on the active site and reaction pathway need to be clarified. Here, we report the design of faujasite-encaged mononuclear Cu centers, namely Cu@FAU, for this challenging reaction. Stable methanol space-time-yield (STY) of 12.8 mmol/gcat/h and methanol selectivity of 89.5% are simultaneously achieved at a relatively low reaction temperature of 513 K, making Cu@FAU a potential methanol synthesis catalyst from CO2 hydrogenation. With zeolite-encaged mononuclear Cu centers as the destined active sites, the unique reaction pathway of stepwise CO2 hydrogenation over Cu@FAU is illustrated. This work provides a clear example of catalytic reaction with explicit structure-activity relationship and highlights the power of zeolite catalysis in complex chemical transformations.
