ABSTRACT:
Disclosed herein is a process for reducing metal salts in which catalyst metal containing ions are reduced to the corresponding metals with a reducing agent which contains a sulfur atom and is relatively weak in reducing ability such as sodium thiosulfate, potassium thiosulfate, ammonium thiosulfate, sodium metabisulfite, potassium metabisulfite and ammonium metabisulfite. Since the reducing agent is weak, the size of the catalyst metals supported on the supports is small to enhance the catalytic activity.
