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

Abstract

Atmospheric water is an abundant source of freshwater and it plays an important role in controlling the available water on land. Emerging atmospheric water generators (AWG) using desiccant materials enable...

Controllable synthesis of N/Co-doped carbon from metal–organic frameworks for integrated solar vapor generation and advanced oxidation processes

“…Global freshwater shortage has become ever impeditive to sustainable development due to the limited freshwater resources and severe worldwide water pollution. [1][2][3][4][5][6] Utilizing non-potable water to produce clean water is deemed to be a primary way to resolve the crisis of freshwater scarcity. 7 Nowadays, various technologies of wastewater treatment are being exploited, such as adsorption, ltration, reverse osmosis, and membrane distillation.…”

Hygroscopic and Photothermal All-Polymer Foams for Efficient Atmospheric Water Harvesting, Passive Humidity Management, and Protective Packaging

“…(ii) One of the polymers’ main advantages is their processability, customizability, and adjustability compared to inorganic desiccants. However, shape-controlled and large-scale fabrication of polymer-based desiccants (i.e., natural and synthetic polyelectrolytes) remains elusive. − Hybrid and system-level design of enlarged hygroscopic areas, efficient water diffusion pathways, high water retention, and rapid water release in 3D hybrid desiccants are still beyond reach. , (iii) Aside from moisture harvesting and clean water production, the integration of polymer-based desiccants into emerging energywise technologies (i.e., humidity control, passive cooling, solar-powered irrigation, and energy regeneration) has attracted growing attention. ,,− We suggest that the excellent mechanical properties of processable polymers would provide a new function for polymer-based desiccants, which can be used as versatile cushioning materials in the protective packaging of humidity-sensitive products (i.e., fruits and electronics). To the best of our knowledge, such a proof of concept has not been reported yet.…”

Highly efficient solar driven cogeneration of freshwater and electricity

“…With the development of industrialization and growth in population, shortages of freshwater and fossil fuel resources are becoming increasingly serious. [1][2][3][4] As an ideal renewable energy source, solar energy has attracted much attention for decades due to its large amount of radiation and inexhaustible advantages. 5 The efficient utilization of solar energy is an important strategy for the sustainable development of human society.…”
