Document Type and Number:
Japanese Patent JP2008506513
Kind Code:
A
Abstract:
A method of production of highly alloyed supported or unsupported platinum-ruthenium catalysts by simultaneous precipitation of the corresponding hydrous oxides or hydroxides and subsequent reduction wherein the simultaneous precipitation of platinum and ruthenium hydrous oxides is made possible by mixing two separate precursor solutions of the two metals, one in acidic and the other in basic environment, until reaching a near-neutral pH at which both hydrous oxide species are insoluble.
