Conventional Heating Versus Microwave Heating (IMAGE)
Caption
(Top) Whereas conventional heating results in a mostly uniform temperature between the platinum nanoparticle and support, microwave heating creates a marked temperature difference. This is revealed by the either gradual or sharp changes in the XAFS spectra as temperature changes. (Bottom) Microwaves selectively heat the metallic nanoparticles in the catalyst and create a temperature gradient that can be indirectly measured via XAFS spectroscopy. In this work, the external and internal temperature differences between nanoparticle and support were determined for two different catalysts, as well as their catalytic performance.
