对于燃煤供能的钙循环再生反应器，燃烧会产生5-20 vol %的水蒸气，从而对钙基材料的脱附产生明显影响。基于此，该工作通过实验考察了水蒸气浓度对吸附剂分解再生的影响规律，发现CaCO3的分解过程中引入水蒸气不仅使CaCO3的再生开始温度降低，同时提升了CaCO3的分解反应速率。进一步基于密度泛函理论，发现H2O在CaCO3表面上的桥位吸附并解离后，H离子与CO3中的O原子形成O-H键后弱化了O-...
Li4SiO4作为高温CO2吸附剂时需要预先进行造粒使其具备良好的抗磨损性与反应器适用性。但是，造粒过程会引起吸附剂颗粒孔结构的坍塌与堵塞，导致CO2吸附性能大幅衰减。基于此，该工作首先筛选多种硅源合成了Li4SiO4原粉，发现气相SiO2作为硅源合成的Li4SiO4粉体材料（F-powder）吸附容量可达0.31 g-CO2/g-吸附剂，且具有最快的吸附速率。进一步采用聚乙烯造孔生产了规则的Li...
