摘要：

The stabilization of metal particles in a recent synthesis of colloidal transition metals was achieved by combining the stabilizing agent (NR ⊕4) with the reducing agent (NR4BEt3H). The disadvantages inherent to this method (the cost of the reducing agent synthesis and the need for stoichiometric amounts of stabilizing agent) have been overcome in the development reported here: NR ⊕4‐stabilized (isolatable) metals of groups 6‒11 are produced by coupling the stabilizing agent to the metal salt that is to be reduced and reducing with simple inorganic and organic reducing agents. These isolatable colloid powders are precursors to highly active homogeneous and heterogeneous metal colloid catalysts. Copyright © 1992 Verlag GmbH & Co. KGaA, Weinheim
