an excellent stabilizer of ruthenium, rhodium, iridium, palladium, and platinum nanoparticles from 1 to 3 nm in size uniformly dispersed in the polymer matrix. The catalytic performance of the resulting metal-polymer composites, [email protected]3+Cl−, is dependent on the metal. This dependence was investigated by assessing the hydrogenation of alkenes and arenes. The utility of [email protected]3+Cl−
