ABSTRACT:
A novel catalyst composition, and process for the preparation of magnetic, catalytic composites to improve catalytic metals utilization. A particulate magnetic alloy of iron or cobalt is contacted with a phosphate ion containing solution and reacted therewith sufficiently to form a surface film thereupon, removed from said solution, preferably dried, then admixed or otherwise incorporated within an inorganic oxide matrix, notably alumina, as inclusions, the composite particle is then contacted with a solution which contains a compound, or compounds, of a Group VIII noble metal, notably platinum, which is deposited within the composite particle in catalytically effective amounts without significant loss of the catalytic metal due to surface deposition of the catalytic metal upon said particulate magnetic alloy inclusions.
