Bimetallic Pt-Re/A1203 catalysts are prepared under hydrogen atmosphere by a surface redox reaction between hydrogen adsorbed on a parent platinum/alumina catalyst and the perrhenate ion ReO 4. This reaction, called catalytic reduction, occurs only in an acidic medium, a maximum rhenium deposition a
