The　direct　production　of　higher　alcohols　from　syngas　in　a　single　step　remains　a　great　challenge.　In　this　work,　a　series　of　K　and　Ni　promoted　Mo2C/Al2O3　catalysts　were　prepared　by　impregnation　method　to　enhance　the　selectivity　of　Mo2C-based　catalysts　for　the　one-step　conversion　of　syngas　to　higher　alcohols.　The　catalysts　were　continuously　tested　under　the　following　conditions:　300　degrees　C,　3.0　MPa,　velocity-11.50　Lg(Mo)(-1　)h(-1),　H-2/CO　ratio　of　2.　The　catalysts　promoted　with　K　and　Ni　demonstrated　the　highest　total　alcohol　selectivity　of　67.7%.　Moreover,　the　selectivity　for　total　C2+　alcohols　reached　as　high　as　56%,　with　37%　being　ethanol.　X-ray　diffraction　(XRD),　hydrogen　temperature-programmed　reduction　(H-2-TPR)　and　X-ray　photoelectron　spectroscopy　(XPS)　characterization　data　reveal　that　K　can　promote　the　crystallinity　of　beta-Mo2C,　lower　the　catalyst　reduction　temperature　and　increase　the　proportion　of　high-valent　Mo　on　the　catalyst　surface.　In　addition,　adding　Ni　as　a　promoter　to　the　KMo2C/Al2O3　catalyst　can　generate　a　synergistic　effect　to　further　enhance　the　catalytic　activity　and　the　selectivity　of　higher　alcohols.
