一系列的四个同构的微孔配位聚合物（MCP）的金属组成不同的表现出卓越的吸收CO（2）在低压和环境温度下。这些条件对于从燃煤发电厂捕获烟道气特别相关。提出了一种镁基材料，其是迄今报道的表面积最高的镁MCP，并且基于对CO（2）的吸附热显示出亲合性。这项研究表明，物理吸附材料可以实现与胺吸附剂竞争的亲和力和容量，同时大大降低与再生相关的能源成本。
A series of four isostructural microporous coordination polymers (MCPs) differing in metal composition is demonstrated to exhibit exceptional uptake of CO(2) at low pressures and ambient temperature. These conditions are particularly relevant for capture of flue gas from coal-fired power plants. A magnesium-based material is presented that is the highest surface area magnesium MCP yet reported and displays ultrahigh affinity based on heat of adsorption for CO(2). This study demonstrates that physisorptive materials can achieve affinities and capacities competitive with amine sorbents while greatly reducing the energy cost associated with regeneration.
