Abstract
Visible light activated photocatalytic degradation of mono-, di- and tri - nitrophenols using Cu2O
Author(s): T. Narasimha Murthy, P. Suresh, A. M. Umabala and A. V. Prasada RaoPhoto catalytic degradation of 4-NP and 2-NP was also achieved over Cu2O under visible light irradiation for 180 and 150 min respectively in presence of external oxidant H2O2. Photodegradation of 2, 4-dinitrophenol and 2, 4, 6- trinitrophenol occurred in 4 hrs and 5 hrs respectively. Presence of H2O2 was found to enhance the rate of degradation in terms of a synergetic effect to generate more ����OH free radicals that help degrade the organic pollutants rapidly. Ease of photocatalytic degradation in the nitrophenols studied has been found to vary in the order 4-nitrophenol > 2-nitrophenol > di-nitrophenol > tri-nitrophenol
