摘要
金属有机骨架(metal organic frameworks,MOFs)应用于吸附式空气取水(adsorption-based at-mospheric water harvesting,ABAWH)技术是解决低湿度条件下空气取水的有效手段.然而目前鲜有对MOFs的系统评价,且缺乏MOFs的热稳定性与毒理性研究.以某沙漠低湿高温的气候条件为研究背景,建立多维评价体系(物理性能、吸附-解吸等温线、水稳定性、热稳定性以及毒理性),采用层次分析法(analyt-ic hierarchy process,AHP)对比研究了 4 种 MOFs 材料(MOF-801、富马酸铝、MIL-100 和 CAU-10H).实验结果表明:比表面积和吸附-解吸性能方面,MIL-100具有明显优势;热稳定性方面,富马酸铝最佳,CAU-10H优于MOF-801和MIL-100;安全性方面,MIL-100和MOF-801更为可靠.综合得出,MIL-100更适合作为ABAWH装置的吸附剂.
Abstract
The application of metal organic frameworks(MOFs)to the technology of adsorption-based atmospheric water harvesting(ABAWH)is an effective means to solve the problem of atmosphere water harvesting under low humidity conditions.However,there are few systematic reviews on MOFs,and there is a lack of studies on the thermal stability and toxicology of MOFs.In this paper,a multi-dimen-sional evaluation system(physical properties,adsorption-desorption isotherm,water stability,thermal stability and toxicity)is established based on the research background of low humidity and high tempera-ture climate in a certain desert.The Analytic hierarchy process(AHP)is used to compare and study four MOFs materials(MOF-801,Aluminum fumarate,MIL-100 and CAU-10H).The main conclusions are as follows.(1)MIL-100 has obvious advantages in terms of specific surface area and adsorption-desorption performance.(2)Aluminum fumarate is best in terms of thermal stability,CAU-10H is better than MOF-801 and MIL-100.(3)In terms of safety,MIL-100 and MOF-801 are more reliable.It is concluded that MIL-100 is more suitable as adsorbent for ABAWH devices.
