Abstract: The main of a book take n-butyl titanate and anhydrous alcohol as main raw material, metal matter, adopt the certain proportion of adulteration Fe3+sum other sol gel law has prepared nanometer TiO2 photocatalyst combining with routine drying legal institutions. Adopt XRD, BET and TEM and so on means face to face catalyst seismic crystal each other, specific surface area and grain diameter size be in progress superficial characteristics, use methyl blue photo catalysis degradation be model reaction mercury lamp lower face to face preparation catalyst catalysis function be in progress valuation. Matter result being demonstrated , adding Ca2 +, the value controlling a pH depends on 3 range , seasoning time is in 24 h , catalyst grain diameter made by calcinations temperature 500 ℃is small , distribution is narrow , specific surface area is big , disperse is good , catalysis effect is best , another , adding Zn2 + preparation also has fairly good catalysis function effect
Keywords: TiO2photocatalyst , sol -gel，n-butyl titanate, anhydrous alcohol， methyl blue
