The catalytic performance of AuxPdy nanoparticles prepared by colloidal synthesis and immobilised on ceria nanorods (Ce-NR) in the selective oxidation of glucose has been studied under initially basic and relatively mild conditions. Activity was found to be strongly dependent on the bimetallic composition with Au-rich catalysts being more active in glucose oxidation. Catalyst recycling revealed
negligible deactivation or metal loss from leaching, and continuing high selectivity to gluconic acid (≥97.7%). Defects on the Ce-NR surface appear to serve as anchoring sites for Au-Pd NPs giving rise to small and very stable NPs.
