![]() The blog that crosses the boundaries between research and the industrial application of gold technology Linking catalyst properties to particle size6 Nov, 2009 This weeks edition of Science carries a nice paper entitled Electronic Structure Controls Reactivity of Size-Selected Pd Clusters Adsorbed on TiO2 Surfaces. What the authors, based at the University of Utah, have demonstrated is the first conclusive link between the size of catalyst particles on a solid surface, their electronic properties and their ability to [...] |
