Optimization of platinum and PtRu colloid syntheses via NR 4 (BEt 3 H) reduction was achieved via the ‘reverse addition mode’. The amount of stabilizing agent could be reduced by 40%. This improvement leads to a better particle size control and a considerable reduction of unwanted organic residues on the metal colloid particle surface. The PtRu catalyst prepared by reverse addition mode shows improvement in the methanol oxidation activity. Copyright © 2005 John Wiley & Sons, Ltd.
