Embodiment 1

[0030] 0.02g Fe(NO 3 ) 3 9H 2O was dissolved in 20 ml of absolute ethanol, stirred to form a uniform solution, 1 g of nonionic surfactant P123 was added, and stirred in a constant temperature water bath at 40 degrees Celsius for 20 minutes until P123 was dissolved to form a clear solution. Then 0.06 g of mercaptopropyl-triethoxy silylating agent MPTES was added, and stirred at 40° C. for 2 h to form a sol. Add 3.40 g of butyl titanate to this sol, stir at 40 degrees Celsius for 2 hours, then add dropwise 22 ml of anhydrous ethanol-water mixed solution [absolute ethanol: water = 10: 1.0 (V / V), Containing 20 ml of absolute ethanol and 2 ml of deionized water], stirred in a water bath at 40°C for 24 hours, evaporated to dryness in a water bath at 80°C for 40 hours, and obtained an orange gel, extracted with 150 ml of ethanol for 12 hours, and filtered to separate a solid sample. The obtained sample was transferred to an autoclave, crystallized in 0.1 M, 40 ml HCl solution at 1...

Abstract

The invention discloses an in-pore hydrosulfide group functionalized ferruginous mesoporous titanium oxide and a preparation method thereof. The titanium oxide comprises inorganic oxide frames of Ti-O-Ti, Ti-O-Fe, Ti-O-Si and alkyl -CnH2nSH which is connected with Si and is substituted by the hydrosulfide group, and the characteristic molecular formula of the titanium oxide is (Fe2O3)x(TiO2)y(SiO3 / 2-CnH2nSH)z, in the formula, X is more than 0.0000 and is less than or equal to 0.0002, y is more than 0.0000 and is less than or equal to 0.01, Z is more than 0 and is less than or equal to 0.00025and n is equal to 1-4. The hydrosulfide group pore wall functionalized ferruginous mesoporous titanium oxide is synthesized by one step in a sol-gel system under the condition of similar neutrality condition, low temperature and home position. The amount of the hydrosulfide groups on the surface of the ferruginous mesoporous titanium oxide can be controlled, specific surface is high; besides, thetitanium oxide is provided with anatase crystal form, high crystallinity and ordered structure, meanwhile, the titanium oxide has visible light responsiveness, can be used as a photocatalyst directlyand can be used as substrate materials by assembling and installing specific organic molecules and biomolecules in the pore to realize further functionalization by chemical reaction. The titanium oxide has wide application prospect in the fields of photocatalysis, nanometer photodevice, medicine transportation, biomolecule carrier, etc.

Description
