Abstract Three catalysts, K-Mo 3 S x , K-Mo 3 S x -NiAc (Ac = acetate) and K-Mo 3 S x -NiL (L = Cl − ), were synthesized using in situ decomposition method, which were applied to the conversion of syngas (H 2 and CO) to higher alcohols. The catalytic results revealed that K-Mo 3 S x -NiAc exhibited a high C 2 + alcohol selectivity of 41.9% and a space-time-yield of 440 mg/g/h, while K-Mo 3 S x -NiL had a dramatically low performance. X-ray photoelectron spectra (XPS) results suggested that the different performances of the catalysts were caused by the formation of new active phase K-Mo-S, and Ni only played a role in the further enhancement of catalytic performance.
