Activation energy of the reaction between hexacyanoferrate (III) and thiosulfate ions catalyzed by platinum nanoparticles

Article Abstract:

A temperature-dependant study is carried out for the platinum-nanoparticle-catalyzed electron-transfer reaction between hexacyanoferrate (III) and thiosulfate ions in the temperature range of 20-70 degree Celsius. The findings indicate that this behavior affected the temperature dependence of the catalytic reaction and the decrease in the catalyst surface area due to the increase of nanoparticle aggregation.

Solvent effects on hole-edge structure for single-wall carbon nanotubes and single-wall carbon nanohorns

Article Abstract:

Two kinds of carbon nanotubes (CNTs) are selected to investigate hole-edge reactivity such as single-wall carbon nanotubes (SWNTs) and single-wall carbon nanohorns (SWNHs). The study is helpful to the understanding of hole-edge chemistry and would enable the production of well-designed carbonaceous materials with high functionality.
