| 英文摘要 | As diversified reaction paths exist over practical catalysts towards CO2 hydrogenation, it is highly desiderated to precisely control the reaction path for developing efficient catalysts. Herein, we report that the ensemble of Pt single atoms coordinated with oxygen atoms in MIL-101 (Pt-1@MIL) induces distinct reaction path to improve selective hydrogenation of CO2 into methanol. Pt-1@MIL achieves the turnover frequency number of 117 h(-1) in DMF under 32 bar at 150 degrees C, which is 5.6 times that of Pt-n@MIL. Moreover, the selectivity for methanol is 90.3% over Pt-1@MIL, much higher than that (13.3%) over Pt-n@MIL with CO as the major product. According to mechanistic studies, CO2 is hydrogenated into HCOO* as the intermediate for Pt-1@MIL, whereas COOH* serves as the intermediate for Pt-n@MIL. The unique reaction path over Pt-1@MIL not only lowers the activation energy for the enhanced catalytic activity, but also contributes to the high selectivity for methanol. |
