Final Analysis: Flame Spray Pyrolysis: A Unique Facility for the Production of Nanopowders

摘要

Flame spray pyrolysis can be used to produce a wide array of high purity nanopowders ranging from single metal oxides such as alumina to more complex mixed oxides, metals and catalysts. The technique was first developed by the research group of Sotiris E. Pratsinis at ETH Zurich, Switzerland (1). Since then it has been used to create new and sophisticated materials for catalysis and other applications (2).Johnson Matthey has developed its own Flame Spray Pyrolysis Facility (Figure 1) which produces a range of nanopowders using the flame spray pyrolysis technique. It has the capacity to produce up to 100 g h?1 of nanopowder product, depending on the material composition, and a number of process variables enable the preparation of well-defined target materials.
