Fischer-Tropsch synthesis (FTS) is an industrial catalytic process that converts a mixture of CO and hydrogen into long-chain hydrocarbons. These products are used as clean transportation fuels and chemical building blocks. The solid catalysts used in the process are complex multi-component systems. Therefore, unambiguously determining the catalytically active phase under reaction conditions remains challenging and thus a topic of debate. The active phase in cobalt-based FTS, including the reaction pathways it catalyzes, has been of industrial and academic interest for many years. It provides direct ways to control the output of the process. The delineation between an active and inactive phase is often unclear, as different phases (i.e., cobalt oxide, carbide, and metal) have different catalytic behavior. This review focuses on cobalt-based FTS materials, with a special focus on the industrially applied cobalt/TiO₂ system. The various cobalt phases are reviewed and discussed with respect to the most recent literature.

Fischer-Tropsch 合成 (FTS) 是一种工业催化过程，可将 CO 和氢气的混合物转化为长链碳氢化合物。这些产品用作清洁运输燃料和化学构件。该过程中使用的固体催化剂是复杂的多组分体系。因此，明确确定反应条件下的催化活性相仍然具有挑战性，因此是一个争论的话题。钴基 FTS 中的活性相，包括它催化的反应途径，多年来一直受到工业和学术界的关注。它提供了控制过程输出的直接方法。活性相和非活性相之间的界限通常不清楚，因为不同的相（即氧化钴、碳化物和金属）具有不同的催化行为。₂系统。根据最新的文献回顾和讨论了各种钴相。
