Abstract

Catalytic activity of gold nanoparticles in a hydrosilylation reaction is controlled by irradiation with UV or visible light. When exposed to UV, the particles aggregate and the catalysis is effectively switched "off". When the particles are exposed to visible light, the particles redisperse and catalysis can proceed.
