The speed of colloidal sol is 100 μ L/s.Step（5）The sonication treatment time is 2h.The particle diameter of TiO 2 particles is smaller, unit matter
The population of amount is more, and specific surface area is bigger, is more carried out on the surface beneficial to light-catalyzed reaction, light-catalyzed reaction speed and effect
Rate is also higher.When the size of particle is in 1~10nm, quantum effect just occurs, becomes quantization particle, cause significantly to prohibit
Band broadens, so that hole-electronics is to will be with dimensional quantum degree with stronger oxidation-reduction ability, catalytic activity
Raising and increase.The quantization of size also makes semiconductor obtain the charge migration speed of bigger, hole and compound several of electronics
Rate greatly reduces, and is conducive to improve the speed of light-catalyzed reaction.Titanium dioxide can only be absorbed and be less than due to the limitation of energy gap
The ultraviolet light of 387nm, in visible light part almost without absorption, this greatly reduces its utilization rate to sunlight.And multiple
After closing graphene oxide, the absorption in visible region is remarkably reinforced.Moreover, the characteristic absorption for comparing titanium dioxide have it is bright
Aobvious red shift, can significantly improve utilization rate of the titanium dioxide to sunlight, so as to improve it after illustrating combined oxidation graphene
Photocatalytic activity.After this result can be attributed to combined oxidation graphene, the energy gap of titanium dioxide narrows, that is,
The formation of Ti-O-C keys, causes it to absorb the sunlight of more low energy.
In addition, after composite silicon dioxide, Titanium dioxide absorption solar energy slightly strengthens, but changes no composite graphite
Alkene is obvious.Analysis reason is probably silica as insulator, to a certain extent titanium dioxide energy gap can be made to broaden, but
Si4+Ion enters titanium dioxide lattice, and part substitutes Ti4+Position, so as to form Ti-O-Si network structures, and network knot
The formation of structure has the separation beneficial to semiconductor photoproduction electron-hole pair and the raising of quantum efficiency, improves light to a certain extent
Catalytic activity.Since absorbance curve of the low concentration aqueous solution of methylene blue in ultraviolet-visible light area is relatively simple, especially can
, only there is an absorption maximum in Jian Guang areas at 665nm, and the maximum excitation wavelength of anatase crystal is in 390nm or so, methylene blue
Do not absorbed in this wave-length coverage, can to avoid the overlapping phenomenon of absworption peak, and methylene blue many material surfaces have compared with
Good absorption property, anti-light degradation capability are stronger, it is easy to it is reacted and is detected, so molten using light degradation methylene blue
Liquid evaluates titanium dioxide, the photocatalytic activity of polyester-cotton fabric after coating.Knitted with methylene blue solution percent of decolourization to assess polyester-cotton blend
Thing automatically cleaning effect, specific method are：The methylene blue solution that 50mL concentration is 20mg/L is fitted into culture dish, respectively 4
Be put into a culture dish the polyester-cotton fabric, coating of titanium dioxide fabric, titania/silica coated fabric of the non-coatings of 1g with
And titanium dioxide/graphene oxide coated fabric.Be placed on illumination under the fluorescent lamp of 20W, liquid level apart from light source center 25cm,
Different time samples, and measures the absorbance change of methylene blue solution at wavelength 650nm with ultraviolet-visible spectrophotometer,
Mapped with the relation of the variable quantity of methylene blue solution absorbance and light application time, and photocatalytic activity is represented with this.Do not having
In the presence of having photochemical catalyst, methylene blue solution concentration under ultraviolet irradiation varies less；Titanium dioxide/oxidation
