Solvothermal-Derived Nanocrystalline TiO₂ Supported Co Catalysts in the Hydrogenation of Carbonmonoxide

Abstract:

Nanocrystalline TiO₂ with the average crystallite sizes of 9 and 18 nm were synthesized by the solvothermal method and employed as supports for preparation of Co/TiO₂ catalysts for CO hydrogenation reaction with various Co loadings between 5-20 wt%. For a similar Co loading, the use of larger crystallite size TiO2 resulted in higher higher CO hydrogenation activities with no influences on the product selectivities. However, an optimum amount of cobalt loading that maximized CO hydrogenation activity of Co/TiO₂ was determined to be at ca. 15 wt.% for both TiO2 crystallite sizes.
