ABSTRACT
Microwave-assisted heating method is used to treat graphite oxide (GO), pyrolytic graphene oxide (PGO) and hydrogen-reduced pyrolytic graphene oxide (HPGO). Pure or doped graphene are prepared in the time of minutes and a thermal deoxygenization reduction mechanism is proposed to understand their microwave adsorption behaviors. These carbon materials are excellent catalysts in the reduction of nitrobenzene. The defects are believed to play an important role in the catalytic performance.

f6: Raman spectroscopy of various nano-carbon materials.

Mentions: Furthermore, heteratoms (N,P,B) could dope into the graphene sheets under microwave irradiation. The dopants in graphene sheets are confirmed by the results of NEXAS (Figure 4) and XPS (Figure 5) and the Raman data (Figure 6) show that the dopants create defects in these materials. These doped graphene-based nano-carbon materials are excellent catalysts in the reduction of nitrobenzene and the B-graphene materials with the biggest ID/IG ratio show the highest catalytic capabilities in this reaction. (Table 2).
