A topology approach to overcome the pore size/volume trade-offs for autonomous indoor humidity control

引用

Science China Chemistry 2024年第9期67卷 2968-2974页

作者： Zhi-Shuo Wang Xue-Wen Zhang Kai Zheng Xiao-Xian chen dong-dong Zhou jie-Peng Zhang MOE Key Laboratory of Bioinorganic and Synthetic Chemistry GBRCE for Functional Molecular Engineering School of ChemistryIGCME Sun Yat-Sen University Chemistry and Chemical Engineering Guangdong Laboratory

Autonomous indoor humidity control is gaining more and more attention but is limited by the trade-offs among pore volume,pore size and water stability of water adsorbents. We solve this problem by using a unique coordination network topology combined with hydrolytically stable M（III） carboxylate clusters. By extending the ligand length from 9.0 to 11.2 and 13.7 ?, the pore volume significantly increases from 0.99 to 1.40 and 1.78 cm3g–1, which proportionally increases the saturated water adsorption capacity. Meanwhile, the pore size slightly increases from 10.4 to 11.0 and 13.5 ?, which restricts the isotherm inflection pressure and hysteresis width to meet the requirement of indoor humidity control. Large single-crystals suitable for Xray diffraction studies were obtained by using Fe（III） salts, while isostructural frameworks with sufficiently high water stabilities were synthesized by using Cr（III） salts, which offer record working capacity of 0.90 and 1.10 g g–1for indoor humidity control.
