METHOD FOR PREPARING NANOCRYSTALLINE MIXED METAL OXIDES AND NANOCRYSTALLINE MIXED METAL OXIDES OBTAINED BY SAID METHOD

摘要

The present invention relates to a process for preparing nanocrystalline mixed metal oxide particles from at least two different starting compounds, comprising the steps of a) introducing a stoichiometric mixture of the starting compounds into a reaction chamber by means of a carrier fluid, b) subjecting the starting compound in a treatment zone under a pulse in the reaction chamber under a pulsating thermal treatment, c) forming nanocrystalline mixed metal oxide particles, d) discharging the nanocrystalline mixed metal oxide particles obtained in step b) to c) from the reactor, the stoichiometric mixing of the starting compounds taking place at a temperature of 50°C. The present invention further relates to a nanocrystalline mixed metal oxide, intended more particularly for use as a catalyst, which is obtainable through the process of the invention.
