METHOD FOR MAKING SUPPORTED METALLIC NANOPARTICLES ON FLUIDISED BED

摘要

The invention concerns a method for preparing supported nanoparticles comprising the following steps: introducing in an adequate solvent a metallic co-ordination complex capable of being decomposed at a temperature less than 200 DEG C, optionally in the presence of a gas reactive under reactive gas pressure less than 3 bars; spraying the resulting preparation in conditions avoiding its decomposition in a fluidised bed containing suspended porous support grains, then breaking down the metallic co-ordination complex optionally in the presence of a reactive gas.
