The accumulation of carbon-based greenhouse gas effects, one of which is carbon dioxide gas (CO2)/methane (CH4), has been identified as the primary cause of global warming. Therefore, investigations into the separation of CO2 and CH4 received significant attention in order to achieve gas separation in industrial facilities. The graphene separation technique also received special attention because of its mechanical properties, which include the uniform dispersion of functional graphene and strong interfacial bonds between the modified graphene. Functional graphene has high thermal stability, and graphene is physically a novel material consisting of carbon atoms in a flat lattice configuration with its thinness and strength. However, the material of graphene is controlled by the chemical composition of its basic graphene oxide. Because of its hydrophilic characteristics and numerous oxygen groups on its surface, GO has been investigated for effective gas separation. This review research examined four designs based on GO-based materials: (1) 3D Hollow GO, (2) Thermally Reduced GO, (3) Multiply Oxidized GO, and (4) 3D Mesoporous GO. When deployed on an industrial scale, each design has unique constraints such as low stability, limited performance improvement, and design optimization. To help overcome these obstacles, this review paper performed a technological mapping of GO-based research based on existing issues. In addition, the highlights of advancements in preparation and assessment procedures, as well as approaches to improving the stability of GO and graphene's future prospects as an alternate gas separation material, are also discussed in detail.
