| 摘要 |
The present invention relates to a process for the preparation of nanocrystalline metal oxide particles comprising the steps of a) the introduction of a starting compound into a reaction chamber by means of a carrier fluid, b) the subjecting of the starting compound in a treatment zone to a pulsating thermal treatment, c) the forming of nanocrystalline metal oxide particles, d) the removal of the nanocrystalline metal oxide particles obtained in steps b) and c) from the reactor, wherein the starting compound is introduced into the reaction chamber in the form of a solution, slurry, suspension or in solid aggregate state. Further, the present compound relates to a catalyst material, obtainable by the process according to the invention, in particular a catalyst material for use in the preparation of methanol from carbon monoxide and hydrogen.
