PREPARATION METHOD OF ANATASE TITANIUM DIOXIDE NANOSHEET VIA CHEMICAL VAPOR DEPOSITION

摘要

Provided in the present invention is a method for manufacturing an anatase titanium dioxide nanoplate having a high energy side exposed through a chemistry vapor deposition method using the spontaneous ignition of two gases having different temperatures. According to the present invention, the mixing gas of hydrogen and titanium tetrachloride is put in the fire at a temperature of the anatase-rutile phase transformation or less and deposited by the chemical vapor method, and a high density anatase titanium dioxide nanoplate with an excellent optical catalyst performance is synthesized by controlling the growth direction of the nanoplate using the silicone to expose the surface having a high surface energy.
