P-aminophenol (4-AP) is an important organic compound, which is widely used as key intermediate in dyes, pharmaceutical industry, etc [1]. At present, 4-AP is synthesized by catalytichydrogenation of p-nitrophenol (4-NP), iron powder reduction and the electro-reduction technology, etc [2-3]. However, the process of catalytic hydrogenation of 4-NP is complicated, which requires corrosive acids and produces large amount of by-products. The reduction reaction by iron powder is difficult for product isolation and accompanied by serious waste pollution. Production of 4-NP is thus obstructed because of these limitations as mentioned above.
In this work, CoFe2O4/graphene nanocomposite was synthesized through hydrothermal process and then identified with different analysis such as FT-IR, XRD, SEM, EDAX, VSM. It was found that theCoFe2O4/graphene nanocomposite exhibited high catalytic activities on the reduction of p-nitrophenol to p-aminophenol in the presence of NaBH4. Furthermore, the composite catalyst can be easily recovered due to its magnetic reparability and high stability.
