Influence of Support Preparation Methods on Structure and Catalytic Activity of Co/TiO2-SiO2 for Fischer–Tropsch Synthesis

---

Abstract
TiO2-SiO2 supports were prepared by various methods including precipitation, impregnation, hydrolysisreflux
and sol–gel, and then cobalt was impregnated on those supports. The properties of various catalysts were
characterized by N2 physisorption, XRD, XPS and TPR. The introduction of TiO2 led to stronger Co-support
interaction, accompanying with the variation of dispersion and reduction degree of cobalt. The catalytic test for F-T synthesis revealed that the addition of TiO2 improved the performance of catalysts prepared by precipitation, impregnation and hydrolysis-reflux, but had a negative effect with sol–gel method.

Keywords: TiO2-SiO2 support
