Abstract

Method for the preparation of nanoparticels of titanium dioxide comprising the steps of adding in an autoclave a predetermined quantity of a titanium precursor to a solvent and in the following adding an acid additive; maintaining the temperature of the solution at a predetermined value, preferably by providing energy to the solution by means of microwaves, for a specific reaction time; carrying out washings with dichloromethane and/or diisopropyl ether and/or methanol and then drying the product obtained.
