Fischer-Tropsch (F-T) synthesis, converting syngas to hydrocarbons, provides a green alternative for fuel production. Cobalt is one of the most intensively studied F-T catalysts due to its great activity, high stability, and relatively low cost. In this mini review, we summarized some recent advancements in the development of cobalt-based F-T catalysts focusing on the effects of particle size, surface oxidation states, crystallography, and bimetallic particles, with emphasis on the research from our group. Furthermore, non-steady state conditions were investigated to access the initial kinetics using chemical transient kinetics (CTK) experiments, which could bring more insights into the reaction mechanism and catalyst design.

费托合成（FT）将合成气转化为碳氢化合物，为燃料生产提供了绿色替代方案。钴由于其高活性，高稳定性和相对较低的成本而成为研究最深入的FT催化剂之一。在这个小型综述中，我们总结了钴基FT催化剂开发的一些最新进展，重点是粒度，表面氧化态，晶体学和双金属颗粒的影响，重点是我们小组的研究。此外，使用化学瞬变动力学（CTK）实验研究了非稳态条件以获取初始动力学，这可以为反应机理和催化剂设计带来更多的见识。
