Magnetic Cellulose/Fe3O4/Co3O4 nanocomposite as a new catalyst was synthesized and characterized by FT-IR, XRD, TGA, SEM, TEM, ICP-AES and VSM techniques. The catalytic activity of this heterogeneous catalyst was studied through one-pot synthesis of 1-((benzo[d]thiazol-2-ylamino)(aryl)-methyl)naphthalen-2-ol derivatives from three component reactions of aromatic aldehydes, 2-aminobenzothiazole, and β-naphthol. This benign and economical nanocatalyst was easily recovered using an external magnet and reused in at least five successive runs with no significant loss of activity and provided clean production in a short reaction time.
