Carbon nanotubes decorated hollow metal–organic frameworks for efficient solar-driven atmospheric water harvesting

MOF supraparticles for atmosphere water harvesting at low humidity

“…PVP shows a negative charge in reaction solution, 32 whereas MIL-101 shows the opposite charge. 33 After 12 hours stirring, the homogeneously dispersed MIL-101 particles were coated with layers of PVP due to the electrostatic attraction. When ZrOCl 2 ·8H 2 O was added to the solution, Zr 4+ was adsorbed onto MIL-101, and the abundance of Zr atoms in the overlap junction revealed the existence of Zr atoms in the surface edge of the MIL-101 core (Fig.…”

Marine biomass-derived, hygroscopic and temperature-responsive hydrogel beads for atmospheric water harvesting and solar-powered irrigation

“…, aerogels, hydrogels, films, fabrics and sponges) is of particular interest. 46–67 Although atmospheric water is considered as a promising solution for the growing scarcity in agriculture, few sorption-based AWGs have been developed for the specific use in solar-powered irrigation. 7,33,34 Design of integrated AWG systems for energy-efficient, water-saving and self-sustaining agriculture is still beyond reach.…”

Hygroscopic photothermal beads from marine polysaccharides: demonstration of efficient atmospheric water production, indoor humidity control and photovoltaic panel cooling

“…Like solar distillation, atmospheric water harvesting also allows sustainable operation taking the benets of renewable solar energy and abundant waste heat. [7][8][9][10] In general, there are two types of fog/dew harvesting methods: passive and active. 11,12 Passive fog/dew condensers rely on accelerating water droplet formation and growth via several biomimicking techniques.…”
