摘要: Abstract The preparation of bimetallic PtRe Al 2 O 3 catalysts was investigated by surface redox reaction between hydrogen adsorbed on a ‘parent’ platinum/alumina catalyst and rhenium ions. Rhenium can be deposited under an inert atmosphere (‘recharge’ method), but the deposit is limited amount irreversibly platinum. When carried out (‘catalytic reduction’), this technique allows to large amounts rhenium. partial pressure hydrogen, temperature reaction, concentration nature salt dispersion monometallic platinum strongly influence kinetic extent deposition catalytic reduction.
