Herein, the feasibility of water-induced deactivation of cobalt-based Fischer-Tropsch catalysts by oxidation is summarized and discussed with the help of thermodynamic predictions. Furthermore, identified mechanisms for hydrothermal sintering and recent findings on water-induced oxidation of metallic cobalt to CoO are discussed. However, the main emphasis of the review concerns the formation of metal-support compounds and the applicability of various in situ and ex situ characterization techniques on their identification. The current literature only provides limited information on the formation and morphology of metal-support compounds in cobalt-based Fischer-Tropsch synthesis due to the challenging (direct) characterization of these phases in spent catalysts. However, X-ray absorption spectroscopy and other advanced techniques have recently provided significant insights into the formation of metal-support compounds in a (simulated) high-conversion Fischer-Tropsch environment, while high-resolution microscopy was successfully applied to elucidate corresponding catalyst morphologies.

在此，在热力学预测的帮助下，总结和讨论了通过氧化使钴基费托催化剂水致失活的可行性。此外，还讨论了水热烧结的确定机制和最近关于水诱导金属钴氧化成 CoO 的发现。然而，审查的主要重点涉及金属载体化合物的形成以及各种原位和非原位鉴定的表征技术。由于这些相在废催化剂中具有挑战性（直接）表征，目前的文献仅提供了关于钴基费托合成中金属载体化合物的形成和形态的有限信息。然而，X 射线吸收光谱和其他先进技术最近为（模拟的）高转化费-托环境中金属载体化合物的形成提供了重要见解，同时高分辨率显微镜已成功应用于阐明相应的催化剂形态.
