With unstable layered K2Ti2O5 as the precursor in the traditional preparation of solid phase sintering
nano/micro-composite TiO2 (TiO2-m) derived from K2Ti2O5 was synthesized via ion-exchange. Supported MoO3/TiO2-m catalysts were prepared by incipient impregnation. Simultaneously
the properties of supports and catalysts were characterized by means of SEM
XRD
BET and TEM. An investigation into the HDS performance of MoO3/TiO2-m catalysts for dibenzothiophene was performed. SEM and XRD results showed that the prepared TiO2-m supports were shaped in nano-scale particle and micron-sized whisker morphology
having the same anatase phase with different morphologies and sizes of TiO2. Compared with pure morphology control sample
HDS tests indicated that Mo catalysts supported on TiO2-m showed the best HDS catalytic activity under relatively mild reaction conditions (310℃
