Abstract

In the present research were characterized anatase particles produced by sonochemical means. The TEM, XRD and SEM confirmed that sonochemical synthesis is an effective method to produced nanometric anatase. Relatively low temperature, 500°C, heat treatments show that anatase can be coarsened from 6.4 nm to 28.3 nm after 72 hours of heat treatment and in the absence of phase transformations. Anatase coarsens following a behavior similar to the one described by the LSW theory. The heat treated anatase particles show significant morphological changes as a function of heat treatment time and this directly affects the surface area of the anatase particles. In addition, the results of the effects of heat treatment on Photocatalytic activity are presented. The characterization of the anatase particles were carried out by means of BET, TGA, XRD, Raman, FTIR, UV-Vis and TEM.
