Spinel catalyst MnFe 1.8 Cu 0.15 Ru 0.05 O 4 with particle size of about 42 nm is an effective heterogeneous catalyst for the oxidation of benzylic alcohols. The substitution of Fe for Cu improves its catalytic activity. Based on the characterization of BET, XPS and EXAFS, two factors influencing the structure and texture of the catalyst caused by the substitution of Cu for Fe may be assumed: physical factor responsible for the increasing of surface area; chemical factor responsible for the transformation of RuO bonds to RuO bonds. β‐Elimination is considered to be an important step in the reaction.
