Title
(EN) METHOD FOR THE SYNTHESIS OF NANOCOMPOSITES BASED ON TIO2 AND CARBONATED NANOSTRUCTURES
(FR) PROCÉDÉ DE SYNTHÈSE DE NANOCOMPOSITES A BASE DE TiO2 ET DE NANOSTRUCTURES CARBONÉES
Abstract
(EN)
The invention relates to a method for the synthesis of a nanocomposite compound comprising TiO2 nanoparticles bound to carbon nanostructures, characterised in that it comprises the following steps: a) mixing carbon nanostructures and at least one TiO2 precursor in a first liquid in order to form a stock suspension; b) nebulising said stock suspension and transporting it into a reaction chamber by means of a gaseous flow; and c) carrying out laser pyrolysis of said stock suspension in said reaction chamber in order to simultaneously form TiO2 nanoparticules and graft them onto the nanostructures.
