Enhanced Capacitive Deionization Exploiting Novel Functionalized Graphene Oxide Electrodes

In this study, a novel functionalized graphene oxide (fGO) is proposed for application in water desalination. The fGO obtained with simple and scalable method. Pristine GO (2-(acryloyloxy)ethyl)trimethylammonium through two-step functionalization. Then, it mixed activated carbon coated onto metallic current collector. Material characterization techniques such as electron microscopy, thermal analyses, infrared spectroscopy are employed to study the physical chemical structures of materials. This process provides porous electrode useful capacitive deionization (CDI). desalination performance compared bare carbons, showing remarkable improvement. final device reaches value around 17 mg g-1 salt removal, charge efficiency 98%. findings from lay groundwork future research, contributing increasing existing knowledge on materials CDI.
