The application of magnetic particles technology for the development of new nanomaterials has received considerable attention in recent years. In this context, the objective of this study is firstly, to prepare new catalytic materials that gather the strong adsorption capacities of carbon nanotubes and magnetic properties of iron, it concerns nanocomposites based on a mixture of carbon nanotubes in a very small amounts and iron oxide. Secondly we want to appear their capacities in catalytic oxidation reactions of phenol. Synthesis under the optimal conditions was carried out at different pH. And the characterization of this new nanomaterial reveals a good specific surface area BET, the identification of carbon nanotubes within the matrix was performed by infrared spectroscopy and transmission electron microscopy. The use of this new material as a catalytic support in catalytic oxidation reactions of phenol indicates the high selectivity of this latter and a yield better than this obtained with iron oxide supported by activated carbon. The good catalyst regeneration of the new catalysis and the improvement in their properties are the interesting parameters for the new type nanomaterials.
