The catalytic activity of Fe/SBA-15 for the oxidation of phenol analogues such as 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), 2-nitrophenol (2-NP), 4-nitrophenol (4-NP) and 2,4,6-trichlorophenol (2,4,6-TCP) was investigated in an aqueous solution. Fe/SBA-15 was prepared by wet impregnation method. The heterogeneous green catalyst was calcined at 823K for 3h before catalytic run in high pressure stirred reactor under defined reaction conditions. Catalytic wet oxidation of 2-CP, 4-CP, 2-NP, 4-NP and 2,4,6-TCP was achieved 80.2, 71.2, 53.1, 62.8, 77.3 % in presence of H2O2 and 85.7, 65.8, 61.9, 63.7, 78.1 % in absence of H2O2, respectively in 15-300 min. The reactions were followed pseudo first order kinetics. It is significant that the catalyst worked well without addition of external oxidant. Some of the products of oxidation were identified with GC-MS analysis and on the basis of the results, probable mechanisms for oxidation have been suggested.
