Abstract

A new CrIII–Schiff base complex of N,N′-ethylene-bis-salicylamide (Salm), supported on acidic alumina, was characterized by chemical and spectral (UV–Vis-DRS and FT-IR) analyses. The comparative catalytic activity of the neat and supported metal complex was evaluated using H2O2 decomposition as the model reaction at varying H2O2 concentration and amount of catalyst which showed a higher activity for the supported metal complex. A preliminary study showed that the supported CrIII(Salm) was also active for the oxidation of phenol using H2O2 as oxidant leading to catechol (selectivity ∼62%) and hydroquinone (selectivity ∼32%) as the major products.
