These nanostructures combine for the first time the beneficial effect of alloying Pd with Ag in a single NC hollow domain with the formation of active sites at the interface with the CeO2 counterpart in an additive manner. The PdAg-CeO2 NCs display excellent alkene selectivity for aliphatic alkynes. For the specific case of hydrogenation of internal alkynes such as 4-octyne, very low over-hydrogenation and isomerization products were observed over a full conversion regime, even after prolonged reaction times. These catalytic properties were remarkably superior in comparison to standard catalysts. The promotion of Ag on the moderation of the reactivity of the Pd phase, in combination with the creation of interfacial sites with the CeO2 moiety in the same nanostructure, is pointed as the responsible of such a remarkable catalytic performance.

]]> Our group receives one of the funding awards from La Marató de TV3 http://www.inorganicnanoparticles.net/our-groufunding-award-from-la-marato-de-tv3/ Mon, 12 Nov 2012 10:21:06 +0000 http://inorganic.wpengine.com/?p=1297 Led by Prof. Puntes, our group partnered with Hospital Clínic to present a project for the last edition of the traditional Christmas fundraising telethon “La Marató de TV3”, whose efforts this time were focused on the regeneration and transplantation of organs and tissues. The project resulted among the 29 selected by La Marató, which formally presented the awards last November 5. The news report from TV3 can be found here:

We participated with the project “Cerium oxide nanoparticles as a new therapeutic tool for tissue regeneration in liver diseases”, coordinated by Dr. Wladimiro Jimenez from the Biomedical Diagnostic Center from Hospital Clínic. Our group will contribute with its expertise in cerium oxide nanoparticles, which preliminary results and applications in other areas indicate that are potentially useful in this case due to their anti-oxidant and anti-inflammatory properties.
