Nano ferrites of the formula MFe2O4 (M = Ni, Cu, Zn), synthesized using sol–gel technique, were employed to catalyze the reductive transformation of nitrophenols to aminophenols. The catalytic reduction was carried out in the excess of NaBH4 as reducing agent in aqueous medium at room temperature. CuFe2O4 and NiFe2O4 were found to be active for the reduction of nitrophenols with significant difference...
