The field of nanoparticle synthesis has matured to the point where very precise control over particle size and morphologies are possible. Through controlled nucleation and growth, unique structures can be created, opening up pathways to highly selective and active catalyst systems with improved metal utilization. However, the synthetic strategies often require structure directing agents or stabilizing agents which can be strongly adhered to the nanoparticle surface, limiting its accessibility for catalytic reactions and thus the envisioned advantages. Poor dispersion can also result when nanoparticle suspensions are loaded on catalyst pellets. As such, there are limits for the use of these techniques to improve metal utilization in commercially viable catalysts. This talk will present a brief overview of some recent nanoparticle applications and highlight how a modification of a standard catalyst preparation technique can result in an unexpected improvement in silver utilization in ethylene oxide catalysts.
