Abstract
Green synthesis of nitrogen nanoparticles. Catalysis is a phenomenon where a reaction is taken through an
alternative pathway involving lesser energy. Thus, it has an energy saving
dimension implicit in its definition. This thesis involves the study of
catalysts, synthesized by the solution combustion method. The fuel required for
the newline combustion is aqueous extract obtained from the leaves of selected
plants which gives added credence to the ecofriendly aspirations that dominated
our work. A series of ceria based nano sized catalyst materials, pure and modified
using rare earth metal oxides, transition metal oxides and a non-metallic substance
have been synthesized by the above method. The catalysts have then been newline
characterized for their composition, crystallinity, morphology, surface properties,
thermal stability etc. The prepared catalysts were subsequently evaluated for their
catalytic and photocatalytic efficacy. The photocatalytic potential of the
catalysts was evaluated on the degradation studies of two dyes Malachite Green
(MG) and Congo Red (CR) under visible light and one antibiotic drug
ciprofloxacin (CIP) under UV light. The catalysts were found to show good photocatalytic
efficiency all the three substances mentioned above. The catalytic efficiency
was evaluated on two chemical reactions. One, the reduction of 4-nitrophenol to
4-aminophenol and the other, the synthesis of compounds of Biginelli reaction.
To achieve maximum reduction the experimental conditions for the catalyst were
optimized. Biginelli reaction involves the condensation of ethyl acetoacetate,
benzaldehyde and urea in presence of modified ceria catalysts to form dihydropyrimidines.
The reaction was performed with different catalysts and the one which gave the
best yield was selected for further optimization of other reaction conditions. Employing
the optimized conditions, a set of different dihydropyrimidinone derivatives
were synthesized by varying the precursor aldehydes and ketones. the study
conducted on Green synthesis of nitrogen nanoparticles and its application on
paddy.
