    Abstract

    Photocatalysis is an emerging research area which can provide solutions for many of the environmental challenges in the world because it provides a simple way to use light to induce chemical transformations. It is a field with a wide range of applications such as mineralization of organic pollutants, water splitting, detoxification, disinfection, and organic synthesis. This thesis details about the synthesis and characterization of nanocomposite which can show enhanced photocatalytic activity. In this thesis, we report the synthesis of Bi₂CuO₄ /BiPO₄ nanocomposite via sonication method. This nanocomposite shows higher degradation of dyes like methylene blue. This enhanced activity is expected due to the formation of p-n junction, which is supported by several analyses and control experiments. In another study, we have synthesized Bi₂CuO₄/carbon dots (C-dots) nanocomposite via hydrothermal method which shows better degradation of dye. The enhanced activity is attributed to the higher surface area and photo induced electron transfer property of C-dots.
