GYR4CO2 · Graphene Nanogyroids, a new technological platform for CO2 capture and sequestration

Addressing the urgent global challenge of reducing atmospheric CO2 concentrations requires the development of efficient technologies for carbon capture and sequestration (CCS). The GYR4CO2 project addresses the urgent need to reduce atmospheric CO2 levels by developing advanced carbon capture and sequestration (CCS) technologies. A central focus is on enhancing CCS performance through innovative solid sorbents, by creating novel polymer-graphene composites with highly ordered porous structures. The project aims to synthesize these composites using co-assembly techniques involving graphene oxide platelets and block copolymers from aqueous dispersions. The target is to form negatively curved sp²-hybridized carbon structures, known as Schwarzites, which mimic the topologies of triply periodic minimal surfaces, particularly gyroid morphologies.By meticulously designing these multiphase composites, the project anticipates that the unique geometries will foster stronger interactions with polymer chains, leading to the development of hierarchically porous nanostructures. While theoretical models of graphene gyroid structures exist, GYR4CO2 seeks to realize these nanomaterials experimentally for the first time. The project will also involve synthesizing novel thiol-ene block copolymers, which will spontaneously assemble into gyroid morphologies and be integrated with graphene nanomaterials.The efficacy of these gyroid structures— purely polymeric, graphene, or composite—will be assessed for CCS performance in both individual gas models and real mixed gas systems. The goal is to achieve a CO2 capture capacity exceeding 4 mmol/g, along with high selectivity against nitrogen, oxygen, and humidity. Success in these areas will pave the way for innovative CCS technologies.Additionally, the project aims to enhance Y.
