Chemistry: Precious little catalyst
D. Wayne Goodman1
Abstract
In gold catalysis, less is more. Bulk gold is an inert metal, but tiny particles containing as few as 55 gold atoms are effective at catalysing the targeted oxidation of hydrocarbons.
Until around 20 years ago, gold was thought to be catalytically inactive. During the past two decades this view has been changed with various demonstrations that vanishingly small particles of gold, 3–5 nanometres in diameter, are highly active catalysts for a range of reactions.
