The selective oxidation can be effe ctively catalyzed using noble m etal nanoparticles.Choosing an appropriate support with well-defined structure and suitable surf ace chemistry is a feasible and effective appro ach to make metal nanoparticles with specific size,shape,structure,and to avoid agglom eration leading to catalytic deactivation.With the intention of successfully synthesizing more efficient heterogeneous catalysts for the selective oxidation,it is extremely important to elucidate the effect of metal nanoparticle configuration,the novel nano-structured suppor t on the catalytic ac tivity for selective oxidation with particular highlights on the interactions between both m etal-metal and metal-support.In this study,Au-Pd bimetallic catalysts will be synthesiz ed and examined in the selective oxidation under aerob ic condition using m olecular oxygen.The unique structure of selected support is found to im prove the stabilization of the metals in the preparation as well as the reaction process.Furthermore,surface ch emistry(metal-support interaction)and synergetic effect in the case of metal alloy catalysts(metal-metal interaction)play a cru cial role in control ling the catalytic perform ance of as-prepared catalysts.Various characterizations will be carefully conducted to look into the ins ights of these catalysts physicochemical properties.
