(2) put into fluorine doped tin oxide (FTO) conductive glass in autoclave, conducting surface tilts to lean against up or down the inwall of reactor and places;
(3) step (1) gained mixing solutions all is transferred to autoclave;
(4) autoclave is put into thermostatic drying chamber and carried out hydro-thermal reaction, hydrothermal temperature is 120 ℃-180 ℃, and soaking time is 2-8 hour;
(5) taking-up autoclave after reaction is completed, the cooling room temperature of being down to;
(6) open reactor, take out the FTO conductive glass, repeatedly rinse with deionized water, until the conductive glass two sides all comes off without powder, be placed in air and naturally dry, obtain the rutile titanium dioxide nano wire film.
300-600 ℃ of calcining 1-10 hour, the product that obtains was compared with calcination product not with the rutile titanium dioxide nano wire film that makes, and degree of crystallinity is constant, nanowire diameter and length variations.
A kind of purposes of rutile titanium dioxide nano wire film is characterized in that: carry out the assembling of solar cell as anode material, perhaps be used for the photocatalytic degradation field of photodissociation water and organic pollutant as photocatalyst.There is photoelectric current to produce under solar simulating radiation illumination the rutile titanium dioxide nano wire film material of preparation.
Compared with prior art, advantage and the positively effect of the technology of the present invention are: the titanium salt that utilizes containing sulfate radicals is as titanium source presoma, but by Situ Hydrothermal method direct growth rutile titanium dioxide nano wire film on the FTO conductive glass, the inventive method is simple, controllability is strong, the titanium salt that has solved containing sulfate radicals is difficult to prepare Rutile Type and the problem of growth in situ titanium dioxide nanowire array on conductive substrates, and when can guarantee that sample degree of crystallinity is constant by the method for calcining, realize the variation of nanowire diameter and length.This technical scheme is not reported at present.
