Abstract:
Self-synthesized novel porous hollow silica nanoparticles (PHSNs) were applied as supports to prepare egg-shell nano catalysts for hydrogenation. By an impregnation method, different catalytic actives, such as Pd, Ag or Pt, and some promoters could be evenly loaded on the external surface, the pore channels and the internal surface of PHSNs. The prepared egg-shell catalysts were tested for CO hydrogenation and showed both improved activity and selectivity over those catalysts prepared with conventional support materials.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
