Abstract
New advances in colloidal and other self-assembly synthetic methods make possible the controlled growth of nanoparticles with well-defined sizes and shapes. Catalysis researchers are now attempting to use this capability to design new catalytic processes.
Authors review results from their attempts to use platinum nanoparticles dispersed on high-surface-area supports to perform selective olefin conversions. Emphasis is given to the surface-science experiments and quantum-mechanics calculations that led them to identify potential variations in selectivity in carbon–carbon double-bond isomerization and hydrogenation reactions with the structure of the metal surface.
