Transition Metal Nanoparticles in Tetraalkylphophonium Ionic Liquids – an Innovative Family of Composite Catalysts

Tetraalkylphosphonium ionic liquids serve as both reaction media and nanoparticle stabilizers for catalysis with transition metal nanoparticles. They also facilitate the redispersion of nanoparticle agglomerates, thereby restoring their catalytic activity, and favoring catalyst recyclability.
