| 英文摘要 | The conversion of CO 2 into methanol has emerged as a promising strategy for addressing climate change and optimizing the utilization of carbon resources. Conventional synthesis methods for Cu -based catalysts, such as coprecipitation, necessitate the consumption of substantial amounts of solvent and meticulous control over preparation conditions, while also being susceptible to deactivation by water during hydrogenation. Therefore, it is crucial to develop a catalyst that can be readily synthesized and exhibits outstanding performance and durability. In this study, we present an ultrafast (only 20 min), solid -phase grinding approach to fabricate CuO-ZnO@CuMOR catalysts for CO 2 hydrogenation to methanol. The resulting catalysts were comprehensively characterized using XRD, XPS, H 2 -TPR, NH 3 -TPD, SEM, HRTEM, and In-situ-FTIR techniques. Notably, the CuO-ZnO@CuMOR catalysts with a distinctive capsule -like structure displayed a high catalytic performance for CO 2 hydrogenation. The byproducts of methane and water produced by the CO 2 hydrogenation process were able to be further converted to methanol through Cu-MOR, leading to a significant enhancement of the methanol selectivity (95.6 %) and CO 2 conversion (22.8 %). Moreover, a long-term test lasting 300 h demonstrated constant catalytic performances and superior durability. |
