Special Issue Information

Dear Colleagues,

This Special Issue comprehensively examines cutting-edge advancements in materials science for CO2 capture, fixation, and storage, addressing the urgent need for efficient carbon sequestration solutions. The collection highlights breakthrough developments across three key material categories: high-performance sorbents including metal-organic frameworks (MOFs), amine-impregnated porous materials, and advanced solid adsorbents; innovative fixation materials such as mineral carbonates and biochar-based composites; and novel storage media featuring engineered porous polymers and hybrid matrix systems. Particular emphasis is placed on the molecular design of materials with tailored pore architectures and surface chemistries to enhance CO2 uptake capacity, selectivity, and cycling stability under realistic operating conditions. The issue also explores integrated approaches that combine capture with storage or utilization, including direct mineralization techniques and catalytic conversion pathways. By presenting both fundamental studies and applied research, this special issue provides a holistic perspective on the development of next-generation CO2 management materials that balance performance metrics with scalability, cost-effectiveness, and environmental sustainability, ultimately contributing to global decarbonization efforts across energy and industrial sectors.

The urgent need to mitigate rising global CO2 emissions demands the development of efficient carbon capture technologies. This study addresses the persistent challenge of sintering-induced performance degradation in CaO-based sorbents during high-temperature CO2 capture. A novel solvent/nonsolvent synthetic strategy to fabricate CaO/CaAl-layered double oxide (LDO) composites was developed, where CaAl-LDO serves as a nanostructural stabilizer. The CaAl-LDO precursor enables atomic-level dispersion of components, which upon calcination forms a Ca12Al14O33 “rigid scaffold” that spatially confines CaO nanoparticles and effectively mitigates sintering. Thermogravimetric analysis results demonstrate exceptional cyclic stability; the composite achieves an initial CO2 uptake of 14.5 mmol/g (81.5% of theoretical capacity) and retains 87% of its capacity after 30 cycles. This performance significantly outperforms pure CaO and CaO/MgAl-LDO composites. Physicochemical characterization confirms that structural confinement preserves mesoporous channels, ensuring efficient CO2 diffusion. This work establishes a scalable, instrumentally simple route to high-performance sorbents, offering an efficient solution for carbon capture in energy-intensive industries such as power generation and steel manufacturing.
