Preparation of MS/MIL-101(Cr) composite material and its properties of atmospheric water collection

In this study, we dispersed MIL-101(Cr) into melamine sponge (MS) by one-step hydro-thermal method and prepared MS/MIL-101(Cr) composite material (MM101CM). It is applied to atmospheric water harvest. The structure and properties of MM101CM were characterized by field emission scanning electron microscopy (SEM), X-ray diffraction (XRD), in situ attenuated total reflection fourier transform infrared spectroscopy (FT-IR) and comprehensive thermal analyzer (TG). The influence of temperature and humidity on atmospheric water collection performance of MM101CM was studied. The composite has good water stability and thermal stability, and its maximum water adsorption capacity can reach 1232 ​g/kg. This study found a simple and effective composite way for metal organic framework materials with hygroscopic properties, which will be conducive to the large-scale application of this kind of materials for atmospheric water collection.
