Microwave-Assisted Synthesis of PtRu/CNT and PtSn/CNT Catalysts and Their Applications in the Aerobic Oxidation of Benzyl Alcohol in Base-Free Aqueous Solutions

Ru promoted the reaction by reacting with surface Pt-hydride species to librating free Pt active sites while adding Sn enhances the electronic interaction. Moreover, acid functionalized CNT was identified as the superior support due to its hydrophilic surfaces, conical stacking structures, and the tubular structure with mesoporous open-ended morphology.
