摘要

作为实现碳减排的关键技术，CO

捕集、封存与利用正发挥着越来越重要的作用。然而，以传统多孔液体进行CO

捕集面临着依赖有机溶剂、成本高和环境不友好等问题。以ZIF-8为吸附质，筛选了稳定剂，调控了稳定剂与ZIF-8的质量比以及ZIF-8固含量（

(ZIF-8)/(

(ZIF-8) +

(水))），构建了ZIF-8/水相多孔吸附体系，并对其CO

吸附性能进行了测试。结果表明，聚乙烯醇（PVA）为优选稳定剂，在

(PVA):

(ZIF-8) = 1.0:0.5、ZIF-8固含量为5%时，体系具备良好的流动性与分散稳定性，在常温常压下（25 °C、101.3 kPa）的CO

吸附量为0.663 mmol/g。经过5次吸/脱附循环后，该体系的CO

吸附量仍保持在初始CO

吸附量的86%以上。本研究将为开发低成本、低能耗且环境友好的CO

吸附体系提供新思路。

Abstract

As a key technology for achieving carbon reduction

capture

storage

and utilization is playing an increasingly important role. However

capture using traditional porous liquids faces problems such as dependence on organic solvents

high cost and environmental unfriendliness. Using ZIF-8 as the adsorption medium

stabilizers were screened

and the mass ratios of stabilizers to ZIF-8 and the ZIF-8 solid contents (

(ZIF-8)/(

(ZIF-8) +

(water))) were adjusted. The ZIF-8/aqueous phase porous adsorption system was constructed

and its CO

adsorption performance was tested. The results show that polyvinyl alcohol (PVA) is the preferred stabilizer. When

(PVA):

(ZIF-8) = 1.0:0.5 and the ZIF-8 solid content of 5%

the system exhibits good fluidity and dispersion stability

achieving a CO

adsorption capacity of 0.663 mmol/g at ambient temperature and pressure (25 °C

101.3 kPa). After five adsorption/desorption cycles

the CO

adsorption capacity remains above 86% of the initial CO

adsorption capacity. This study will provide new ideas for developing low-cost

low-energy and environmentally friendly CO

capture systems.
