Abstract: Phenol and its analogues originate from a large number of sources, like the effluents of the petroleum and petrochemical industries, Kraft Mills, Olive Oil production, and various chemical industries manufacturing phenolic resins, herbicides, pesticides, solvents, paints, plastics and other chemicals. These compounds have adverse effects on public health and are non-biodegradable. The best alternative for treating these recalcitrant pollutants has been the wet catalytic oxidation. The present work investigated transition metal (Fe(III), Co(II), Ni(II) and Mn(II)) incorporated MCM41 as catalysts for wet oxidation of phenol and its analogues. The work consisted of (i) Preparation of mesoporous MCM-41 with incorporation of Fe, Co, Ni, Mn into the framework sites, (ii) Characterization of the catalysts with spectroscopic and other techniques, (iii) Catalytic activity study for wet oxidation of phenol, 2-chlorophenol, 4-chlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol, 2-nitrophenol and 4-nitrophenol in water, (iv) Optimization of the reaction conditions, (v) Analysis of the products and establishing the mechanism of oxidation, (vi) Examining leaching characteristics of the catalysts for evaluating their green chemistry role. The thesis is divided into six chapters, viz., Introduction, Experimental Methodology, Characterization of the catalysts, Wet oxidation reactions, Conclusion and References. The first chapter (Chapter 1: Introduction) gives a brief introduction to the types of organic pollutants in water in particular reference to the persistent and toxic phenolic compounds and discusses the ways to treat water contaminated with these compounds. The chapter reviews the oxidative treatment of phenolic waste water with particular reference to Fenton and Fenton like reactions, photo-Fenton reactions, wet oxidation and catalytic wet oxidation. Various mechanisms proposed to explain catalytic wet oxidation are discussed along with those of the familiar Fenton and Fenton-like reactions. Selection of catalysts...
