Researchers find controls to gold nanocatalysis

Structures of a gold cluster (depicted by yellow spheres) containing 20 atoms, adsorbed on a magnesium oxide bed ( magnesium in green and oxygen in red) which is itself supported on top of a molybdenum substrate (blue spheres). The excess electronic charge at the interface is depicted in pink and the charge depletion is shown in light blue. Credit: Uzi Landman/Georgia Tech
