SYNTHESIS AND CHARACTERIZATION OF POROUS MATERIALS TO PERFORM PL AND UV STUDIED OF THEIR INTERACTION WITH ORGANIC DYES

Abstract

With the facts demonstrated through various applications, Zinc Oxide Nanoparticles have proved to own great potential for high porosity and high surface area to volume ratio. The synthesis of mesoporous zinc oxide nanoparticles by hydrothermal and sol-gel methods is achieved in the present work. By following these methods we have obtained two types of nanospheres different in their porosity of the same metal oxide. The modifications are created based on the interactions of the reacting species by following diverse chemical mechanisms. We have performed distinct characterization techniques like XRD, SEM, TEM and Raman to carefully examine their morphologies. As zinc oxide is known to possess optical properties, we have performed its UV studies to explore its interactions with the organic dyes. We have also analysed its photo-degradation behaviour.
