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 m/g, and the pore volume is 0.05-0.4 cm/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.

Mesoporous composite titanium oxide and a preparation method

The invention relates to a system for verifying geographical descriptiveness of a media file, such as a picture. The system comprises storage means adapted to store a media file, communication means adapted to send said media file to a plurality of user terminals, and to receive, from the user terminals, data indicating a guessed geographical position with which the user of each user terminal associates the media file. The system also comprises calculation means adapted to determine whether the media file is indicative of a geographical position based on the guessed geographical positions received from the plurality of user terminal.

Method and system for verifying geographical descriptiveness of media file

A method for preparing titania or precursor thereof with a controllable structure from micropore to mesopore is provided. The method is characterized in that the alkali metal titanate as raw material is reacted for 0.5&#x2dc;72 hours in the wet atmosphere with humidity of 2&#x2dc;100% at temperature of 20&#x2dc;250&#xb0; C., then washed with water or acid, finally performed by air roasting or solvent thermal treatment. The method has advantages that the raw material is easy to be obtained, the conditions and preparation are controllable, the pore structure may be adjusted from micropore to mesopore, crystal mixing and doping are easy, reacting time is short, preparing cost is low, and the said method is suitable for large scale production and so on. The most probable aperture of titanium oxide or precursor thereof with a controllable structure from micropore to mesopore is in the range of 1&#x2dc;20 nm, the pore volume thereof is in the range of 0.05&#x2dc;0.4 cm/g, and the specific surface area thereof is more than 30 m/g. The titania is at least one of anatase-phase titania, TiO(B)-phase titania and rutile-phase titania.
