Mild and selective catalytic oxidation of organic substrates by a carbon nanotube-rhodium nanohybrid

A heterogeneous catalyst was assembled by stabilization of rhodium nanoparticles on carbon nanotubes. The nanohybrid was used for the catalytic aerobic oxidation of diverse substrates such as hydroquinones, hydroxylamines, silanes, hydrazines and thiols, at room temperature. The system proved very efficient on the investigated substrates and demonstrated high selectivity.

CARBON BLACK AS AN ELECTRON-TRANSFER CATALYST - THE TWO-PHASE DEHYDROGENATION OF HYDRAZO NITRILES BY AN AQUEOUS SOLUTION OF POTASSIUM HEXACYANOFERRATE(III), USING CARBON BLACK AS THE CATALYST.

The two-phase(aqueous and organic phase) dehydrogenation of hydrazo nitriles by an aqueous solution of potassium hexacyanoferrate(III), using carbon black as the catalyst, was carried out at 40 degree C with shaking. In the presence of carbon black, the two-phase dehydrogenation of hydrazo nitriles was accelerated, and the corresponding azo nitriles were obtained in good yields. The catalytic activity of channel blacks was larger than that of furnace blacks. Moreover, the increasing content of phenolic hydroxyl groups tended to increase the catalytic activity of carbon blacks. It became apparent that phenolic hydroxyl groups on the surface of carbon black act as an electron-transfer catalyst in the two-phase dehydrogenation.
