Abstract

The residue compounds of Br 2 in three different grades of spectroscopic grade graphitic carbon were studied as oxidation catalysts. Oxidation kinetics measurements showed reduction in activation energies as large as 70% in the less graphitic material. Magnetic susceptibility measurements as a function of oxidation (burn-off), and extent of oxidation after residue compound formation, were performed. The diamagnetism was reduced after the electron acceptor residue compound was formed. The diamagnetic susceptibility value for the pristine sample was recovered after burn-off, suggesting the extent of penetration of the residue compound into the grains of the polycrystalline samples.
