Summary
Carbon dioxide capture from industrial flue gases remains a cornerstone of global climate mitigation strategies, particularly in hard-to-abate sectors such as power generation, cement production, and steel manufacturing. CaO-based adsorbents employed in calcium looping processes offer compelling advantages, including high theoretical uptake capacity, compatibility with high-temperature streams, low material costs, and the use of abundant natural precursors.
Nevertheless, conventional materials face critical limitations, notably rapid performance decay due to sintering and structural degradation during repeated operation. This Special Issue of the journal provides a dedicated platform to advance the field by exploring innovative solutions through next-generation CaO-based adsorbents.
We warmly invite original research articles, reviews, and perspectives covering the following key topics:
- Development of novel synthetic and modified CaO-based sorbents
- Advanced synthesis routes such as sol–gel, combustion, and templating methods
- Stabilization strategies via doping and composite formation with metal oxides
- Design of nanostructured and hierarchically porous architectures
- Strategies to enhance long-term cyclic stability and reaction kinetics
- Reduction of regeneration energy demands and process efficiency improvements
- Utilization of waste-derived and sustainable precursor materials
- Mechanical strength, attrition resistance, and performance in fluidized-bed systems
- Tolerance to flue-gas impurities and realistic operating conditions
- Process integration, scale-up studies, and techno-economic evaluations
- Artificial intelligence and machine learning approaches for sorbent optimization
