Method for preparing mesoporous crystal titanium dioxide using light-sensitive active matter as formboard

The invention relates to a mesoporous TiO2 Crystal Preparation method with a photosensitive activity as template, it belongs to chemical engineering technology. Use of titanium alkoxides or ion-containing titanium ions titanate or salts or mixtures of these substances as TiO2 precursor, ethanol or acetone or a mixture of both as the diluents, used ethylene glycol or isopropyl alcohol or a mixture of both as dispersant, used Perylenequinone derivatives or other natural extract with photosensitive activity as the photosensitive activity object; the titanium dioxide precursor hydrolysis and crystal to get the mesoporous TiO2 precursor; mesoporous TiO2 precursor was sintering to get mesoporous TiO2 Crystal with photosensitive activity as template. The mesoporous materials of this invention through sol-gel method and the high-temperature burning, do visible catalyst, or get carbon nm tube by the separation and purification. The invention has low cost of production, product higher catalytic activity, stable performance, simple process.
