  • 摘要: 随着全球气候变暖和能源需求的持续增长,CH4-CO2重整(dry reforming of methane, DRM)反应作为一种有效的碳捕获与利用技术受到了广泛关注。Ni基催化剂因在此反应中表现了出色的活性和选择性而备受关注。金属-载体相互作用(Metal-Support Interaction, MSI)作为影响Ni基催化剂性能的重要因素,近年来得到了广泛的研究和讨论。本文综述了Ni基催化剂上MSI最新研究进展及其在催化反应中的表征与调控策略。基于MSI角度,介绍了不同载体(金属氧化物、碳材料及分子筛等)对Ni活性金属颗粒分散性和表面结构的影响,重点讨论了MSI对Ni基催化剂上DRM反应活性与稳定性性能的影响。未来的研究应致力于进一步理解和精确控制MSI以提高Ni基催化剂在CH4-CO2重整反应中的性能和稳定性,推动其在清洁能源领域的应用。

     

    Abstract: With ongoing global warming and increain energy demands, the CH4-CO2 reforming reaction (dry reforming of methane, DRM) has garnered significant attention as a promising carbon capture and utilization technology. Nickel-based catalysts are renowned for their outstanding activity and selectivity in this process. The impact of metal-support interaction (MSI), on Ni-based catalyst performance has been extensively researched and debated recently. This paper reviews the recent research progress of MSI on Ni-based catalysts and their characterization and modulation strategies in catalytic reactions. From the perspective of MSI, the effects of different carriers (metal oxides, carbon materials and molecular sieves, etc.) are introduced on the dispersion and surface structure of Ni active metal particles, and the effect of MSI on the activity and stability of DRM reactions on Ni-based catalysts is discussed in detail. Future research should focus on better understanding and controling MSI to improve the performance and durability of Nickel-based catalysts in CH4-CO2 reforming ,advancing cleaner energy technologies.
