Multishelled CaO microspheres coated with an atomic‐layer‐deposition‐grown Al₂O₃ layer yield high‐capacity CO₂ sorbents with improved cyclic stability, as demonstrated by Christoph R. Müller and co‐workers in article number 1702896. The central void formed by the removal of the carbonaceous template accommodates the large volumetric changes of the material during cyclic operation, whereas the porous shells composed of Al₂O₃‐coated CaO nanoparticles reduce diffusive transport limitations through the growing product layer of CaCO₃ and improve the thermal stability of the sorbent.

氧化钙：通过Al2O3的原子层沉积来稳定的多壳CaO微球，用于增强的CO2捕获性能（Adv。Mater。41/2017）

Christoph R.Müller及其同事在产品编号1702896中证实，涂有原子层沉积生长的Al ₂ O ₃层的多层CaO微球可产生具有改善的循环稳定性的高容量CO ₂吸附剂。通过去除碳质模板，可以适应材料在循环运行过程中的大体积变化，而由Al ₂ O ₃包覆的CaO纳米颗粒组成的多孔壳则减少了通过生长的CaCO ₃产物层的扩散传输限制，并提高了热稳定性。吸附剂。
