The selective oxidation of alcohols to the corresponding aldehydes or ketones,in particular benzyl alcohol to benzaldehyde,can be effectively catalyzed using noble metal nanoparticles.Choosing an appropriate support with well-defined structure and suitable surface chemistry is a feasible and effective approach to make metal nanoparticles with specific size,shape,structure,and to avoid agglomeration leading to catalytic deactivation.With the intention of successfully synthesizing more efficient heterogeneous catalysts for the selective oxidation of alcohols,it is extremely important to elucidate the effect of metal nanoparticle confinement inside the novel nano-structured support on the catalytic activity for selective oxidation of alcohols with particular highlights on the interactions between both metal-metal and metal-support.In this study,Au,Pd,Pt monometallic and Au-Pd bimetallic catalysts will be synthesized by confining the active phase (metal nanoparticles) into various pristine and surface-functionalized nanomaterials,such as SBA-16,TUD-1 and CNT.The supported noble metal catalysts will be examined in the selective oxidation of various alcohols under aerobic condition using molecular oxygen.The unique structure of selected support is found to improve the stabilization of the metals in the preparation as well as the reaction process.Furthermore,surface chemistry (metal-support interaction) and synergetic effect in the case of metal alloy catalysts (metal-metal interaction) play a crucial role in controlling the catalytic performance of as-prepared catalysts.Various characterizations will be carefully conducted to look into the insights of these catalysts’ physicochemical properties.
