Abstract
A mesoporous composite titanium oxide, which is composed of a mesoporous titanium oxide, the outside surface and the wall of pores of the mesoporous titanium oxide are modified by inorganic matters; inorganic matter contains at least one element selected from carbon, silicon, sulphur, phosphorus and selenium in an amount of 0.01%-25%, on amount of the element mass, of the mass of said mesoporous composite titanium oxide material; at least one mean pore size of pore distribution of the mesoporous compound titanium oxide material is 3-15 nm, the specific surface area is 50-250 m2/g, and the pore volume is 0.05-0.4 cm3/g. As a catalyst carrier, the rate of conversion of the hydrodesulfurization reaction of the material reaches as high as 98 percent, and as a lithium ion battery cathode material, the specific capacity of the lithium ion battery cathode material reaches as high as 220 mAh/g.
