The ambient environment is a huge treasure with various energy sources (such as solar energy, thermal energy, air flow, atmospheric humidity, etc.) that can be tamed to meet human energy demands for the development of a sustainable society. The atmospheric humidity, which has been viewed as a potential free source of freshwater, is a rather overlooked ambient source because of their annoying attributes, and in most of the cases additional energy must be consumed to reduce the levels of it, to provide a comfortable living space for human. Upon considering that the earth's atmospheric humidity (13000 trillion liters) is estimated equals to 10% of the total volume of all fresh water lakes, the efficient water harvesting from atmospheric humidity can service as a promising available source for safe freshwater. Here in this work, we demonstrate that a 2D MOFs van der Waals heterostructures [Zn(CNS)2(pyz)2]n/ [Co(CNS)2(pyz)2]n (pyz pyrazine) can efficient atmospheric-water harvesting, through an external energy-less humidification dehumidification (HDH) approach. The present 2D MOFs van der Waals heterostructures are capable of adsorbing over 500% of its own weight with water from humid atmospheres, and desorption of the adsorbed water can be achieved by using low-grade heat (≈45℃) from sunlight with exposure time of about 15 min. Compared with other approaches for water harvesting, such as condensation water by using hydrophobic surfaces, disinfection and decontamination the contaminated water sources by using special structures, and desalination of seawater by using salt sorption materials, the present approaches represents the real "energy-free" process of atmospheric water harvesting and delivering.
