Abstract
The economic use of noble metals as catalysts usually requires them to be in the form of extremely small particles, typically less than 100 Å in size. This article reviews methods for the preparation and characterisation of such particles, and their importance in catalysis. For certain limited classes of reaction, activity per unit of surface area is itself a function of particle size; possible bases for explaining this effect are discussed.
