Once thought inert, gold has been recognized during the past decade as a powerful catalyst for oxidations and other reactions. Calculations and experiments have indicated that the catalytic activity of nanosized gold clusters containing only a few atoms of the precious metal should be extremely high. But scientists haven’t had an optimal way to prepare and study them, until now. Avelino Corma of the Institute of Chemical Technology at Polytechnic University of Valencia, in Spain, . . .
