Studies on Synthesis of Nanoparticles and their Applications

Abstract

newline Field of Nano science is continuously evolving and nanoparticles are in huge demand to newlinebenefit many practical and industrial applications. With a probable ambiguity in the choice newlineof nanoparticles between synthetic and biological origins, recent interests of nanomaterial newlinefraternity is showcasing a positive inclination towards usage of green, biological and newlineecofriendly sources for nanoparticles synthesis which not only benefits the material newlineprocessing cost and brings in quality but also benefits the environment in the product life newlinecycle. In this work, focus is laid on the synthesis of nanoparticles of two important newlinematerials such as titanium dioxide and silica through bottom-up approach and their newlineapplications in the field of waste water treatment by removing unwanted materials like newlineheavy metals ions and dyes from the aqueous solution is explored. TiO2 is preferred widely newlinein environmental purification applications due its simple, abundant, strong oxidizing and newlinenon-toxic nature whereas SiO2 nanoparticles due to their chemically inert nature, high newlinesurface areas, UV transparency and great physical stability act as one of the best support newlinematerials . Details of the experiments performed, characterization done and results obtained newlineare included in detail and the subject matter contained in this thesis is organized in eight newlinedifferent chapters.
