Synthesis, Stability, Electronic and Catalytic Properties of Micellar Metal Nanoparticles: Size, Support and Oxidation State Effects Beatriz Roldán Cuenya Department of Physics, University of Central Florida, Orlando, FL 32816 The next generation of nanocatalysts requires detailed knowledge of the correlation between their structure, chemical composition, and reactivity. To study these effects, large quantities of homogeneous and size-selected nanoparticles are needed.
