Claim Text:
1. A mesoporous composite titanium oxide material for a catalyst carrier or a lithium ion battery cathode comprising: a mesoporous titanium oxide, which has a specific surface area of 90-250 m wherein an outside surface of the mesoporous titanium oxide and wall surfaces of pores of the mesoporous titanium oxide are modified by a process to form a mesoporous titanium oxide having a composite layer on its outside surface and pores with composite layer on their wall surfaces; the process is as follows: dissolving a precursor containing at least one element of Si, C, S, P and Se in water or organic solvent to form solution, adding mesoporous titanium oxide into the solution and stirring for 1-72 hours then filtering and washing with water or organic solvent, and carrying out sintering in an atmosphere at 300-900° C.; mass of the at least one element of Si, C, S, P and Se is in an amount of 0.01%-25% of a mass of said mesoporous composite titanium oxide material; at least one mean pore size of pore distribution of the mesoporous composite titanium oxide material is 3-15 nm, a specific surface area is 90-250 m morphology of the mesoporous composite titanium oxide material presents crystal whiskers, fiber or particles with the diameter of 0.1-10μm.
