DNP signal enhancement factors up to 170 enable gaining deeper insight into the surface chemistry of Pt-NPs. Carbon monoxide is used as a probe molecule to analyze the adsorption process and the surface chemistry on the supported Pt-NPs. The studied systems show significant catalytic activity in carbon monoxide oxidation on their surface at room temperature. The underlying catalytic mechanism is the water-gas shift reaction. In the case of alumina as the support the produced CO2 reacts with the surface to form carbonate, which is revealed by solid-state NMR. A similar carbonate formation is also observed when physical mixtures of neat alumina with silica, fumed silica and titania supported Pt-NPs are studied."}],"user_id":"100715","_id":"63991","language":[{"iso":"eng"}],"extern":"1","keyword":["Chemistry","gamma-alumina","hydrogenation","silica","c-13","interactions","metal-catalysts","particle-size","platinum nanoparticles","sites","surface","water-gas shift"]}
