The overconsumption of fossil energy sources has resulted in serious environmental impacts and an ensuing energy crisis. Therefore, the search for a new alternative energy technology has become a focus of attention. The long-established Fischer-Tropsch synthesis technology and the recent CO hydrogenation technology with unlimited potential seem to be among the ways to solve the above problems. Among them, the development of efficient Fe-based catalysts has become a key issue. Weaker interactions on carbon supports are more favourable for the formation of active phases in Fe-based catalysts than stronger metal-support interactions on conventional oxide supports. In this work, we systematically summarise the application of various types of carbon materials (carbon nanotubes, mesoporous carbon, graphene, activated carbon, etc.) in CO hydrogenation reactions. The effects of different structural types of carriers on the dispersion of active sites are discussed. At the same time, the effects of different carrier preparation methods on catalytic performance are compared. In addition, the role of surface modifications to carbon materials in the promotion of active sites is discussed. Finally, we propose possible research directions based on the current problems in these catalytic systems. The aim is to provide a reference for the development of new carbon materials and their application in CO hydrogenation.
化石能源的过度消耗已造成严重的环境影响及随之而来的能源危机。因此，寻找新的替代能源技术已成为关注焦点。久负盛名的费托合成技术以及潜力无限的近期CO加氢技术似乎是解决上述问题的途径之一。其中，高效铁基催化剂的开发已成为关键问题。与传统氧化物载体上较强的金属-载体相互作用相比，碳载体上较弱的相互作用更有利于铁基催化剂中活性相的形成。在这项工作中，我们系统总结了各类碳材料（碳纳米管、介孔碳、石墨烯、活性炭等）在CO加氢反应中的应用。讨论了不同结构类型载体对活性位点分散的影响。同时，比较了不同载体制备方法对催化性能的影响。此外，还讨论了碳材料表面改性在促进活性位点方面的作用。最后，基于这些催化体系当前存在的问题提出了可能的研究方向。目的是为新型碳材料的开发及其在CO加氢中的应用提供参考。
