Abstract

This paper summarizes the effects of microwave heating for formation of local high temperature at the supported metal nanoparticles. We demonstrated the enhancement of catalytic dehydrogenation of 2-propanol over supported Pt catalysts. Then, we discussed the mechanism of microwave heating caused by supported Pt nanoparticles using a substrate system. Furthermore, microwave in situ XAFS was used to estimate the local temperature of Pt nanoparticles. We found that the local temperature of Pt was 26-132 K higher than that of the bulk. From these results, we concluded that the microwave irradiation causes localized high tempretaure at the supported nanoparticles and enhance heterogeneous catalytic reactions.
