Abstract:
1. A one-pot polyol process for making particle complexes, the process comprising: synthesizing a plurality of particles in a sol-gel process to form a particle suspension; functionalizing the surface of the plurality of particles in the particle suspension, whereby functionalized groups capable of immobilizing silver nano-clusters are formed on the surface of the silica particles; adding, without separating the plurality of particles from the particle suspension, a polyol to form a polyol suspension; mixing a source of metal ions into the polyol suspension; reducing the metal ions to form a metallic phase; and nucleating metal nano-clusters on the surface of the plurality of particles functionalized during the step of functionalizing, to form the particle complexes.
