Abstract Scope |
Carbon capture and storage can effectively prevent the release of CO2 into atmosphere, causing air pollution and greenhouse effect. Developing the materials that can separate CO2 from power plant flue or product gases and store it securely is a primary task. Manganese dioxide octahedral molecular sieve (OMS) has demonstrated this potential application. It is comprised of the columns of edge-sharing of MnO6 octahedra with alternating 1 × 1 and m × n tunnels. First-principles density functional theory-based calculations have been applied to study the OMS materials. As the size of the OMS tunnel changes, comprehensive studies have been conducted to reveal its atomic structure, electronic and magnetic properties, and predict CO2 adsorption and diffusion mechanisms in comparison with experimental measurement. |
