Abstract

A new, highly capable and dynamic aerogel adsorbent for CO2 capture was developed using a one-step sol-gel process along with solvent exchange and supercritical drying. The highest CO2 adsorption capacity in a 1% CO2 flow stream (5.55 mmol g(-1)) is much higher than other aerogel adsorbents obtained using a 10% or even higher CO2 gas mixture.

摘要

通过一步溶胶-凝胶法以及溶剂交换和超临界干燥，开发出一种用于二氧化碳捕集的新型、高性能且动态的气凝胶吸附剂。在1%二氧化碳气流中，其最高二氧化碳吸附容量（5.55 mmol g⁻¹）远高于使用10%甚至更高二氧化碳气体混合物制得的其他气凝胶吸附剂。
