| abstract |
The present invention relates to particularly simple to produce heterogeneous catalysts which are generated by in situ immobilization of preformed mono- or multimetallic metal oxide particles on an oxidic or non-oxide support. For this purpose, hydroxide ion-stabilized metal oxide colloids are generated from common, water-soluble metal salts by hydrolysis and condensation and are immobilized on carriers present in the suspension. With this method u. a. Manufacture fuel cell catalysts. |
