PROCESS FOR SYNTHESISING NANOPARTICLES OF MESOPOROUS AND HOLLOW MAGNETITE OF HIGH SUPERFICIAL AREA IN A SINGLE STEP BY THE AEROSOL ASSISTED CHEMICAL VAPOUR DEPOSITION TECHNIQUE.

摘要

The present invention refers to the obtention of magnetite manoparticles having a hollow and mesoporous structure, which were obtained by the aerosol assisted chemical vapour deposition process, using a precursor solution containing an organic or inorganic salt that contains Fe and a suitable solvent. The synthesis is performed at a temperature of from about 200°C and 900°C, using a mixture of inert and oxidant gases as dragging gas. The nanoparticles obtained by this method are collected and washed with methanol in an ultrasonic bath for being subsequently used.
