Heteroatom Doped Graphene Composite for Inorganic Sensing and Environmental Remediation

Abstract

The efficient removal of organic and inorganic pollutants from water through ecofriendly adsorption and absorption techniques is a critical concern in environmental newlinescience. Current methods for eliminating dyes and heavy metals from contaminated newlinewater are often inefficient, non-recyclable, and environmentally harmful. Moreover, newlinetwo-dimensional (2D) graphene Nanostructures commonly used for such applications newlinesuffer from aggregation and restacking issues due to strong and#960;-and#960; and hydrophobic newlineinteractions. Graphene also exhibits a limited surface area compared to heteroatomdoped newlinegraphene, and its lack of intrinsic bandgap restricts its potential uses. Heteroatom doping can introduce diverse physiochemical, electromagnetic, optical, electrical, thermal, and structural properties to graphene. The objective of this research is to develop an eco-friendly synthesis technique for heteroatom-doped graphene by exploring the utilization of non-toxic sources. newlineFurthermore, we aim to investigate the applicability of heteroatom-doped graphene newlineand its composites with metal oxide (titanium dioxide) and magnetic nanoparticles newline(Fe3O4) for the efficient removal of dyes and heavy metals from polluted water. newlineIn this study, we propose a simple and eco-friendly strategy for the preparation of newlineheteroatom-doped graphene using green doping sources. To the best of our newlineknowledge, this is the first report to employ green sources for the synthesis of newlineheteroatom-doped graphene, demonstrating excellent adsorption capacity for dyes and newlineheavy metals with remarkable recyclability. Additionally, we explore the fascinating properties of heteroatom-doped graphenecomposites with metal oxide (titanium dioxide) and magnetic nanoparticles (Fe3O4). The synergistic adsorption properties of heteroatom-doped graphene, metal oxide, and magnetic nanoparticles, coupled with their superior recyclability, offer substantial advantages over current approaches. The utilization of heteroatom-doped graphene and its composites presents novel opportunities for the removal of
