The modification of titanium in mesoporous silica for Co-based Fischer-Tropsch catalysts
文献摘要：
Ordered SBA-15 mesoporous silica with incor-porated titanium was successfully synthesized via a one-pot hydrothermal crystallization method.The characteriza-tion including powder X-ray diffraction,Brunauer-Emmett-Teller,transmission electron microscope,temperature-programmed reduction,temperature-programmed desorp-tion,Fourier transform infrared and ultraviolet-visible-near infrared spectrometer was performed to explore the physical and chemical structures of both the supports and the catalysts.The results showed that titanium was success-fully incorporated into the mesoporous silica framework with a limited amount of titanium(Si/Ti＞20),and the mesoporous structure was retained.However,the increased titanium content inevitably resulted in the formation of anatase TiO2 particles on the support surface.The increased incorporated titanium strengthened the interac-tions between cobalt species and supports,which was favorable for the cobalt species dispersion,despite the limited cobalt oxide reducibility.The enhanced metal-support interactions were beneficial for the CO/H2 ratio at the active cobalt sites,which facilitated the formation of more C5+hydrocarbons.This study provides a promising method for support modification with incorporated-heteroatoms for the rational development of Fischer-Tropsch catalysts.
