摘要：

In this study, a CO2 capture material in the form of liquid-like adsorbents (LLAs) is developed to overcome the limitations of conventional types of adsorbents. The increase in indoor activities necessitates the capture of CO2 in enclosed indoor spaces. Indoor spaces require safe and stable materials for CO2 capture because humans are present in these spaces. Solid adsorbents are mainly used because liquid absorbents are unsuitable owing to noise and scattering problems. In LLA, the liquid absorbent assembled by carbon nanotubes (CNTs) is solidified and prevented from flowing and scattering indoor. LLAs present to maintain 95% of initial capacity after recycling 20 times, and have characteristics that can be regenerated in a low temperature heat source (80 to 120.) and moisture resistance. This work not only provides indoor useable CO2 capture materials, but also offers a new prospect in the field of adsorbents.
