Multifunctional carbon dots-based nanocomposites for sustainable environmental management and solar-driven water evaporation

Abstract

The investigation outlined in the thesis entitled “Multifunctional Carbon Dots Based Nanocomposites for Sustainable Environmental Management” was launched in August 2020 at the Department of Chemistry, Indian Institute of Technology Indore. The aims of this thesis are to design and develop multifunctional carbon dots and nanocomposites for pollutant remediation and water purification through sensing, photocatalytic degradation, and interfacial solar-driven water evaporation. The main points of the thesis are as follows- 1) Modulation of green and chemical source-derived carbon dots through a post-synthetic reduction strategy for metal ion sensing. 2) Design a portable and non-invasive fluorescent thin film from Cascabela thevetia-derived carbon dots for picric acid detection. 3) To develop a hybrid platform from carbon dots anchored bacterial cellulose for the environmental remediation of pharmaceuticals. 4) To engineer a multifunctional photothermal membrane from carbon dots incorporated into bacterial cellulose for interfacial solar-driven water evaporation and purification. 5) To fabricate a photothermal membrane by integrating carbon dots-based organic network into bacterial cellulose for interfacial water evaporation.
