英文摘要	Water harvesting from the atmosphere using adsorption-based technology holds great promise to solve water scarcity in arid regions. Birnessite (i.e., a layered structure MnO2) can store water molecularly between its layers, providing a path for water adsorption. This work investigates the water sorption characteristic of birnessite from both thermodynamic and kinetic perspectives. The water vapor adsorption on bimessite follows a Type II sorption isotherm. Water molecules quickly adsorb to the interlayers at lower RH region values, while multilayer water-water interactions occur via hydrogen bonding at surfaces and result in condensed water at higher RH. Furthermore, birnessite features excellent solar absorptivity; the temperature can be raised by 87 degrees C under solar irradiation at a sun flux of similar to 900 W/m(2), providing energy to trigger partial desorption of interlayer water. According to the Do and Do model simulation, birnessite can harvest 0.07 kg of water per kilogram of sample (kg(H2O)/kg(Sample)) per cycle at RH of 23% when the dew point temperature is set to 11 degrees C. Finally, a device based on the concept of sorption-based atmospheric water harvesting is built to present this application. This inexpensive water adsorption material with solar absorptivity displays an applicable promise for solving water scarcity in arid regions.
