Cobalt carbides have been recognized as an active phase for the production of light olefins and alcohols in Fischer–Tropsch synthesis. In this study, in situ X-ray diffraction experiments were performed to investigate the stability and catalytic performance over a single-phase Co₃C catalyst under reaction conditions. The in situ X-ray diffraction results indicated that the Co₃C phase remained stable with no significant changes until the temperature reached 300 °C. The high stability can be attributed to the twinning structure of the single-phase Co₃C catalyst. The catalytic evaluation results showed that the single-phase Co₃C catalyst had higher activity with high selectivity to long-chain products due to the unique surface structure of Co₃C. This work provides guidance for the rational design of efficient cobalt carbide catalysts for Fischer–Tropsch synthesis reactions.
