The catalytic conversion of synthesis gas derived from coal, natural gas or renewable biomass is among the most promising routes to produce alternative energy carriers and chemical feedstocks. Although production of diesel fuel and methanol from syngas has been well-developed on a world scale, there is still a growing need for the direct synthesis of mixed alcohols. When properly promoted by alkali metals, molybdenum carbide is considered to be a promising catalyst for alcohol synthesis from syngas. However, the importance of catalyst nanostructure and the role of the promoter are unclear. This study utilizes X-ray absorption spectroscopy and diffuse reflectance infrared Fourier transform spectroscopy to characterize the atomic structure and CO adsorption characteristics of alkali-metal-promoted nanoparticles of Mo2C supported on Al2O3, which demonstrate high selectivity towards mixed alcohols during CO hydrogenation.
