Platinum nanoparticles adsorbed inside carbon nanotubes are far more effective catalysts for asymmetric hydrogenation than particles adsorbed on nanotube exteriors or conventional support materials, according to researchers in China (Angew. Chem. Int. Ed., DOI: 10.1002/anie.201006870). The technique of incorporating catalysts into nanotubes may lead to improved methods for making chiral pharmaceutical compounds.

Nearly all highly enantiospecific catalytic reactions are mediated by solution-phase (homogeneous) catalysts. Heterogeneous catalysts could offer several key advantages over their solution-phase . . .
