Preparation of Polymer-Stabilized Noble Metal Colloids.

A series of polymer-stabilized platinum and palladium colloids were prepared via methanol reduction for the investigation of the preparation conditions. Through TEM observation and catalytic hydrogenation of olefins, it was found that adding a suitable amount of NaOH was good for small-sized colloidal particles and higher catalytic hydrogenation activity.
