PRECIOUS METAL SALT SOLUTIONS AND PRECIOUS METAL CATALYSTS

摘要

According to the disclosure, solutions of precious metal salts of organic carboxylic acids are prepared by reacting an organic carboxylic acid with a hydrated precious metal oxide in an organic solvent for both the acid and the carboxylate salt. The process results in high purity solutions which can be used as such as very effective precious metal catalysts. Alternatively, the precious metal carboxylates can be recovered and converted into oxides or elemental metal products by decomposition or reduction and giving rise to products having enhanced surface area and small particle clusters, and also useful as very effective precious metal catalysts.
