Solvent-free selective aerobic oxidation of toluene by ultra fine nano-palladium catalyst Original Research Article

High activity ultrafine Pd catalyst was synthesized by both functional polymer encapsulated and impregnation methods. Catalysts were characterized and used to catalyze solvent-free aerobic toluene oxidation. Reaction temperature, time, catalyst mass, air pressure and catalyst reusability were investigated. Catalyst synthesized by encapsulating and immobilizing Pd inside titanium oxide is more active and has a better reusability.
