Insight into the key factors of β-Mo₂C catalyst for the reverse water gas shift reaction.

ABSTRACT: In this study, we found that β-Mo₂C prepared at different carbonization temperatures exhibited significantly different catalytic activities for the reverse water gas shift (RWGS) reaction. The β-Mo₂C synthesized at 600 °C demonstrated notably higher activity compared to those prepared at 700 °C and 800 °C. This enhanced activity was likely attributed to its improved redox properties, which were primarily driven by a smaller crystallite size and the presence of Mo _x OC _y species. Therefore, we proposed that the crystallite size and Mo _x OC _y content were the key factors governing the RWGS activity of β-Mo₂C. Clearly, both factors were strongly influenced by the carbonization temperature.
