چکیده

Faceted platinum nanocrystals supported on carbon nanotubes were prepared using NO2- as a crucial shape-controlling agent. The composites exhibit high electrochemical catalytic activity for oxygen reduction facilitated by the cooperation between the Pt{111} facets and atomic steps, and extremely high selectivity for the oxidation of glycerol to glyceraldehyde.

Effects of Confinement in Carbon Nanotubes on the Performance and Lifetime of Fischer-Tropsch Iron Nano Catalysts

The effects of confinement in carbon nanotubes on Fischer-Tropsch (FT) activity, selectivity and lifetime of Carbon NanoTubes (CNTs) supported iron catalysts are reported. A method was developed to control the position of the catalytic sites on either inner or outer surface of carbon nanotubes. TEM analyses revealed that more than 80% of iron oxide particles can be controlled to be position...
