New Paper on High-Index Surface Platinum Hollow Nanocrystals Published in Journal of Materials Chemistry A.
One of the main focus of the group is the development of synthetic strategies for the production of advanced hollow NCs allowing the precise morphological control of its surface. This aspect, of critical importance for the understanding of the unique properties of the materials at the nanoscale, is also useful in a wide range of applications, such as catalysis, where the development of highly active and low-cost materials represents a landmark for the development of industrial technologies. This time we show how combining solid state chemistry techniques and colloidal synthesis allows us to prepare exotic materials, such as PtAg@Pt single-crystal hollow NCs with high-index planes, at room temperature (green temperature) by controlled corrosion of silver templates, which minimize Pt consumption and maximize surface reactivity. We are further working on the applicability use of these NC-based catalysts. The work, carried out with the collaboration of Prof. Jordi Arbiol from the Catalan Institute of Nanoscience and Nanotechnology (ICN2), has now been published in Journal of Materials Chemistry A under the title ” Enhanced reactivity of high-index surface platinum hollow nanocrystals“
