The Fischer–Tropsch product, water, is regularly hypothesized to be the driving force for catalyst deactivation. Cobalt nanoparticles may be oxidized to CoO, form mixed-metal oxides with supports, or sinter to larger particles. This Comment discusses the feasibility of these deactivation pathways, highlighting the importance of in situ characterization.

水诱导的钴基费-托催化剂失活

费-托产品水通常被认为是催化剂失活的驱动力。钴纳米颗粒可被氧化成CoO，与载体形成混合金属氧化物，或烧结成更大的颗粒。该评论讨论了这些失活途径的可行性，强调了原位表征的重要性。
