Abstract

Metal–organic frameworks (MOFs) are a class of promising nanomaterials for atmospheric water harvesting (AWH), especially in arid remote areas. However, several challenges are still faced for practical applications because of the dissatisfied water adsorption/desorption properties in terms of the capability, kinetics, and stability. Herein, we report the facile synthesis of a nano-sized octahedral nitrogen-modified MOF-801 that exhibits superior solar-powered AWH performance using a custom-made device, with a state-of-the-art water harvesting ability up to 4.64 L H 2 O kg MOFs 1 from air upon 12-h test under a relative humidity (RH) of 30% and simulated sunlight irradiation. The nitrogen-modified MOF-801 with rapid sorption–desorption kinetics, uptakes 0.29 g H 2 O g MOFs - 1 of water at 30% RH within 30 min and releases 90% of the captured water within 10 min under 1-sun illumination. The success relies on N-doping-induced mixed-linkers in the form of 2,3-diaminobutanedioic acid and fumaric acid in the unique pore structures of the MOFs for rapid and high-capacity water capture. The N-doped MOF-801 with water uptake capacity, fast adsorption kinetics, and cycle stability sheds light on the practical use of MOFs for effective solar-powered water harvesting from droughty air.

用于从干旱空气中收集水的太阳能混合连接剂金属有机框架
金属有机框架(MOFs)是一类很有前景的大气集水(AWH)纳米材料,尤其适用于干旱偏远地区。然而,由于MOFs在吸附/解吸水能力、动力学和稳定性等方面的特性不尽人意,其实际应用仍面临一些挑战。在此,我们报告了一种纳米级八面体氮修饰 MOF-801的简易合成方法,该方法利用定制的装置表现出了卓越的太阳能供电 AWH 性能,其最先进的集水能力可达 4.64LH2OkgMOFs-1$$ 4.64\kern0.5em {\mathrm{L}}_{{m\mathrm{H}}_2\mathrm{O}}\kern0.5em {{\mathrm{kg}}_{{m\mathrm{MOFs}}^{-1}$$ 在相对湿度(RH)为 30% 和模拟太阳光照射下进行 12 小时测试后,MOF-801 从空气中收集的水量达到 4.64LH2OkgMOFs-1$$ 4.64\kern0.5em {\mathrm{L}}_{{m\mathrm{H}}_2\mathrm{O}}\kern0.5em {{\mathrm{kg}}_{{m\mathrm{MOFs}}^{-1}$$氮修饰的 MOF-801 具有快速的吸附-解吸动力学,在 30% 的相对湿度(RH)和模拟太阳光照射条件下,从空气中吸收 0.29gH2OgMOFs-1$$ 0.29\kern0.5em {\mathrm{g}}_{{\mathrm{H}}_2\mathrm{O}}\kern0.5em {{\mathrm{g}}_{\mathrm{MOFs}}^{\hbox{-}1}$ 在 30% 相对湿度下,30 分钟内释放出 90% 的水,在 1 个太阳光照射下,10 分钟内释放出 90% 的捕获水。这一成功依赖于 MOF 独特的孔隙结构中以 2,3-二氨基丁二酸和富马酸形式存在的 N 掺杂诱导混合连接体,从而实现了快速、高容量的水捕获。掺杂了 N 的 MOF-801 具有吸水能力、快速吸附动力学和循环稳定性,这为实际利用 MOFs 从干旱空气中有效收集太阳能水提供了启示。
