Photooxidation of Benzene to Phenol by Al2O3-Supported Fe(III)-5-Sulfosalicylic Acid (ssal) Complex

Abstract

Selective oxidation of benzene with H 2 O 2 to phenol has been developed using a novel Fe(III) complex bearing 5-sulfosalicylic acid ligands immobilized alumina catalyst under visible light irradiation. The catalyst activity was evaluated by the photooxidation of benzene to phenol. The results indicate the best result with 100% conversion of benzene and 27.64% selectivity for phenol at low catalyst loading (0.7 mmol/g alumina). The catalyst was used for at least 4 cycles without any appreciable loss of activity.

“…These functional groups indicate the presence of carbon in the Al 2 O 3 films. 36 The broad band that appeared at 3670 cm −1 is due to the surface-bonded hydroxyl groups (O−H), which play an important role in the growth of Al 2 O 3 ALD films. 37 3.4.…”

Oxidative degradation of dinitro butyl phenol (DNBP) utilizing hydrogen peroxide and solar light over a Al2O3-supported Fe(III)-5-sulfosalicylic acid (ssal) catalyst

“…Based on this observation and the results of our earlier experiments [16], a reasonable mechanism for the photocatalytic degradation DNBP, in the Fe(III)-ssal-Al 2 O 3 /H 2 O 2 system under visible light irradiation is outlined in Fig. 10.…”

“…In our recent study [16], we reported a novel kind of catalyst, [Fe(III)-ssal]-Al 2 O 3 , made by supporting the complex Fe(III) 5-sulfosalicylic acid (ssal) onto Al 2 O 3 . This Al 2 O 3 supported Fe(III) complex having 5-sulfosalicylic acid (ssal) ligand was found to be an efficient catalyst for the direct hydroxylation of benzene with hydrogen peroxide under visible light irradiation.…”

“…The peak at 1117 is ascribed to the functional group of Al‐O‐Al . In addition, the carbonyl group (C‐O) has appeared at 1250 cm −1 , and the CO group at 1710 cm −1 , indicating the presence of carbon in the Al 2 O 3 films . The band at 3670 cm −1 is attributed to the surface‐bonded hydroxyl groups (O‐H), which play an important role in the growth of Al 2 O 3 ‐grown ALD films .…”
