摘要
Here, we report a high-performance catalyst MoS x @HSSZ-39 for conversion of CO x to C 2–4 hydrocarbons, in which MoS x clusters for CO x hydrogenation at the first to intermediate methanol and then the zeolitic acid sites surrounding for further conversion of methanol to hydrocarbons. For CO 2 hydrogenation, C 2–4 hydrocarbons of ∼90% selectivity in organic products at 32.7% of CO 2 conversion and excellent stability of 1000 h on stream are obtained. For CO hydrogenation, 95% of C 2–4 hydrocarbons, 83% of LPG or 74% of propane selectivities at > 22% CO conversion and stable more than 200 h on stream are obtained. The cooperation among the MoS x clusters and the zeolitic acid sites constitutes the catalyst of intimate bifunction, which is the key to the high catalytic performance for CO x hydrogenation.
