Enhancing catalytic performance of AuPd catalysts towards the direct synthesis of H 2 O 2 through incorporation of base metals

The introduction of small quantities of tertiary base metals into supported AuPd nanoparticles results in improved catalytic performance towards the direct synthesis of H 2 O 2 , compared to the bi-metallic analogue. This enhanced activity can be attributed to the electronic modification of Pd and t...

Summary:The introduction of small quantities of tertiary base metals into supported AuPd nanoparticles results in improved catalytic performance towards the direct synthesis of H 2 O 2 , compared to the bi-metallic analogue. This enhanced activity can be attributed to the electronic modification of Pd and the formation of domains of mixed Pd oxidation state. In particular the introduction of Ni is observed to result in initial rates of H 2 O 2 synthesis, where the contribution from competitive degradation reactions is negligible, in excess of three times that achieved over the supported AuPd catalyst.
