Pd-Au bimetal supported on rutile-TiO2 for selective synthesis of hydrogen peroxide by oxidation of H2 with O2 under atmospheric pressure

Rutile TiO2 support is effective for increasing the formation rate as well as selectivity to H2O2. A great enhancement in the H2O2 formation rate and selectivity is achieved by controlling the particle size of Pd-Au (7:3 in weight ratio) alloy, and the average size of 18 nm exhibits the high selectivity to H2O2 under atmospheric pressure.
