CO2 Capture using Functionalized Graphene Oxide

In this work, we aim to address the urgent global issue of increasing CO2 levels. We conduct a comprehensive study that integrates both experimental and theoretical chemistry. Using Density Functional Theory (DFT) first-principle calculations, we determine the positions of functional groups on the graphene lattice. Furthermore, we investigate the nature of interactions between functionalized-Graphene Oxide and CO2 molecules, from first principles. We synthesize various types of functionalized-graphene membranes for CO2 capture and perform physical and chemical analyses using X-ray Diffraction (XRD), Proton Nuclear Magnetic Resonance (H-NMR), and Fourier Transform Infrared Spectroscopy. Our results demonstrate effective CO2 capture using amino-functionalized graphene under stationary conditions, consistent with theoretical predictions.
