An attempt has been made to review and study the effect of anions (phosphate, sulfate and fluoride) on titania-silica samples. A comparative study has been made on structural characteristics and physico-chemical properties between the unmodified and anion modified titania-silica mixed oxides. The stabilisations of phase, porosity and sulphate ion at higher activation temperatures are discussed. The increase and decrease of specific surface area, acid strength and surface acid sites with respect to anions are emphasised. The effect of preparation method and conditions with specific surface area, porosity and surface acid sites are also discussed. The generation of new catalytic active sites and effect of porosity are reported towards esterification of acetic acid and mono-nitration of toluene, respectively.
