A novel catalyst was prepared by carbonization of Botryococcus braunii (B. braunii) residue. In this study, reductive reaction of nitrobenzene was carried out with a catalyst based on biomass residues. The carbons from B. braunii residues allow production of aniline from nitrobenzene. This is the first research of development of a catalyst from carbon containing magnetic components, which was produced from a flocculant contained biomass residues. Mass production of oil from B. braunii has been paid much attention in view point of development of new energy source. However, the oil extracted B. braunii residues are still large amount of Fe3O4 and carbon with industrial treatment as a catalyst for reduction of nitroarene.
