The anatase TiO2(a-TiO2) nanoparticles with controlled size have been successfully prepared by a facile solution phase method without using any surfactants, employing titanium isopropoxide as precursors in various alcohol (methanol, ethanol, propanol and butanol) media. Both XRD and Raman results revealed that the products are the phase of anatase TiO2. Morphological studies performed by TEM showed that the products were nanoparticles with the particle size in the range of 5–20 nm, the size of a-TiO2nanoparticles could be easily turned by changing the types of alcohol. The photocatalytic activity studies of the a-TiO2nanoparticles demonstrated their excellent performance in photodegrading methylene blue and bisphenol aqueous solution by using UV-A light irradiation. This higher photocatalytic activity of the a-TiO2nanoparticles was mainly attributed to the smaller particle size. |
