Morphology Study of anatase nano-TiO2 for Self-cleaning Coating

Abstract

Titanium dioxide (TiO2) has been widely used in the field of pollutant degradation, virus ‎killer and environment protection. In this paper, the 8 nm TiO2 nanoparticles are first ‎synthesized by TiOSO4.2H2O precursor. The samples were then characterized by x-ray ‎diffraction (XRD) and transmission electron microscopy (TEM) analysis and Raman ‎scattering after heat treatments. The XRD results show the sharp picks of the samples after ‎annealing. The SEM results show that the size of nanoparticles is about 8 nm in diameter. ‎Finally Raman scattering pattern of the as-prepared TiO2 indicates the anatase phase
