Nanoparticles as Semi-Heterogeneous Catalyst Supports

Nanoparticles can serve as semi‐heterogeneous supports since they readily disperse in common solvents and combine high surface area with excellent accessibility. Reversible agglomeration through solvent changes and magnetic separation provide technically attractive alternatives to classical catalyst filtration. This account places emphasis on recent developments in this emerging area. High surface area, excellent accessibility, and the ability to readily disperse in common solvents facilitate the use of nanoparticles as semi‐heterogeneous supports.
