  • SYNTHESIS METHOD FOR TIO2 NANOCRYSTAL
    Publication number: 20170267542
    Abstract: Provided is a method for synthesizing TiO2 nanocrystal, comprising: adjusting the pH value of a colloidal suspension of tetratitanic acid nanosheet as a precursor to 5-13; and subjecting the precursor to a hydrothermal reaction to obtain the TiO2 nanocrystal. The TiO2 nanocrystal synthesized by the method is anatase-type, and the exposed crystal facet thereof is {010} crystal facet. The method has advantages of low cost, no pollution, simple synthesizing process, strong controllability, short production period and good reproducibility, and is suitable for industrial production.
