F210. Co and NiPd nanoscale catalysts
Left: (a) TEM image of Co nanoparticles on a silica support; (b) a diagram of particle distribution. Right: (a): TEM image of NiPd nanoparticles on a silica support showing the size and morphology of the particles. The inset is a typical HRTEM image of NiPd nanoparticle; (b): a diagram of particle distribution. These nanoparticles, derived from colloidal precursors and supported on commercially available non-ordered mesoporous silica, are highly effective, cheap, recyclable and industrially viable catalysts for the hydrogenation of a range of nitro-substituted aromatics under mild conditions.
