Method of preparing high crystalline nanoporous titanium dioxide photocatalyst |
摘要 |
Disclosed is a method of preparing high crystalline nanoporous titanium dioxide photocatalyst, capable of preparing the high crystalline nanoporous titanium dioxide photocatalyst in mass production through a simply synthesis method using an ultrasonification. The method includes the steps of (a) mixing a titanium precursor and a surfactant in a first solvent and performing a sol-gel reaction; (b) maturing a reactant obtained through the sol-gel reaction for 15 hours to 25 hours; (c) filtering the matured reactant and washing the matured reactant; (d) primarily drying the washed reactant at a temperature of 20° C. to 50° C. to obtain titanium sediments; (e) mixing the titanium sediments in a second solvent and performing an ultrasonification with respect to the mixed solution for 10 minutes to 120 minutes; and (f) secondarily drying the mixed solution, which has been subject to the ultrasonification, at a temperature of 15° C. to 45° C. to obtain titanium dioxide photocatalytic particles.
