摘要:
A method for producing a titanium dioxide photocatalyst is provided. The method uses a sol-gel process wherein acid and base catalysts are added in two separate steps. According to the method, a titanium dioxide photocatalyst with increased mesoporosity can be produced without the use of any particular additive. Further, an anatase structure is formed upon drying and is maintained even after high-temperature calcination. Further provided is a titanium dioxide photocatalyst produced by the method. Further provided is a titanium dioxide photocatalyst doped with sulfur and zirconium, which is produced by using the method. The doped titanium dioxide photocatalyst exhibits catalytic activity even under visible light and excellent surface characteristics to achieve improved photocatalytic activity.

Disclosed is a method of preparing ZSM-5 having substantially 100% crystallinity by using variable temperatures in the absence of an organic template, characterized in that a reaction mixture having a molar composition of M2O/SiO2 (M: alkali metal ion) of 0.07-0.14, H2O/SiO2 of 15-42 and SiO2/Al2O3 of 20-100 is nucleated at relatively high temperatures (180-210° C.) and then crystallized at relatively low temperatures (130-170° C.), thus easily controlling a crystal size and a particle size distribution of the ZSM-5.
