In this work, a facile hydrothermal route was used to prepare nano‐sized MoS 2 catalyst. The effect of citric acid during the MoS 2 preparation process on the catalytic activity of sulfur‐resistant CO methanation was investigated. It was found that citric acid played an adverse role on the catalytic activity of MoS 2 toward sulfur‐resistant CO methanation. However, CO methanation performance turned out to be better when NH 2 OH⋅HCl as a reductant was removed during the catalyst preparation process. The X‐ray diffraction (XRD) and infrared spectroscopy (IR) were performed to discuss the possible mechanism for the effect of citric acid towards CO methanation performance.
