Abstract:119 Sn Mössbauer spectroscopy at 77 K was used to observe surface tin atoms on PtSn x /SiO 2 catalysts. Two families of PtSn x /SiO 2 catalysts with fully reduced Pt (0) and Sn (0) atoms were prepared following the Surface Organo-metallic Chemistry on Metal strategy. These two families of catalysts exhibit about the same Sn/Pt composition, but very different metallic particle diameters, each with narrow particle size distribution, so that, the ratio between surface tin atoms and "bulk" tin atoms was significan… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
