| The “precursor” concept of catalyst preparation involves the deposition of colloidal metals onto a support. This approach offers the advantage that the metal catalyst can be characterized in terms of particle size and size distribution prior to deposition. Through variations of the preparation procedure and the stabilizer, a wide range of precursors can be prepared including decorated surfaces, bimetallic and core/shell particles. One of the principal obstacles that must be overcome in order to fully utilize this approach is the removal of the stabilizer. Here, we will present recent developments in the preparation of heterogeneous catalysts using metal colloids as precursors. |
