Abstract:
in the present study, we have prepared and evaluated the physical and
chemical properties and catalytic activities of transition metal loaded sulfated
titania via the sol-gel route. Sol-gel method is widely used for preparing porous
materials having controlled properties and leads to the formation of oxide
particles in nano range, which are spherical or interconnected to each other.
Characterization using various physico-chemical techniques and a
detailed study of acidic properties are also carried out. Some reactions of
industrial importance such as Friedel-Crafts reaction, fen-butylation of phenol,Beckmann rearrangement of cyclohexanone oxime, nitration of phenol and
photochemical degradation of methylene blue have been selected for catalytic
activity study in the present venture.
The work is organized into eight chapters

Abstract:
Catalysis is a mature field with extensive practical applications in today's society.indeed,the catalysis of petroleum refining,fine chemical synthesis and emission control demands the production of catalysts in bulk quantities.Future improvement of these well established processes is likely to be incremental.On the other hand,the continuous demand for new products will require additional novel and innovative processes.The need for pollution abatement and prevention also imposes new demands on catalysis, and new processes are periodically advanced for the control of emission of gases as well as for remediation processes such as the cleaning of underground waters. The number of problems where catalysis can have a big impact is constantly growing.In general,science stimulated by the technology has enriched the field of catalysis in a way that has had broad and lasting value.The thesis"Transition metal and rare earth metal modified sol-gel titania: a versatile catalyst for organic transformations" accounts the preparation and characterization studies of both transition metals and rare earth metals modified sol-gel titania and its applications in industrially useful organic reactions.
