基于浸渍有聚乙烯亚胺（PEI）的气相二氧化硅的易于制备的固体材料被发现是用于直接从空气中捕获二氧化碳的上级吸附剂。在实验的最初几个小时，这些吸附剂有效地从空气中清除了所有的二氧化碳，尽管它的浓度非常低。在室温下研究了水分对吸附性能和吸附容量的影响。再生能力也确定在一个短系列的吸附/解吸循环。
Easy to prepare solid materials based on fumed silica impregnated with polyethylenimine (PEI) were found to be superior adsorbents for the capture of carbon dioxide directly from air. During the initial hours of the experiments, these adsorbents effectively scrubbed all the CO2 from the air despite its very low concentration. The effect of moisture on the adsorption characteristics and capacity was studied at room temperature. Regenerative ability was also determined in a short series of adsorption/desorption cycles.
