Biogenic Carbon Dots for Potential Use in Dye Reduction "a Greener Way of Environmental Remediation"

EasyChair Preprint no. 2833

Abstract

A greener and environmentally sustainable way for water remediation is reported here, which utilizes nanomaterials prepared from waste materials "the orange peel".  The synthesis of water soluble and fluorescent C-dots, a new promising class of biocompatible and multicolor luminescent nanoparticles, from waste such as orange peels through low temperature microwave process has been reported. The prepared C-dots are of 5 nm and they show strong fluorescence. The synthesized C-dots have been characterized by using DLS, UV-Visible, FT-IR, XRD, Fluorescence measurement techniques. The synthesized C-dots are found to be effective catalyst for the reduction of Eosin Y and Methylene Blue with NaBH₄ as the reducing agent. A detail pathway for step by step reduction, oxidation of dyes was established by UV-Vis spectroscopy.
