Super Moisture‐Sorbent Sponge for Sustainable Atmospheric Water Harvesting and Power Generation

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 7, 2024

Sorption-based atmospheric water harvesting (SAWH) shows great promise to mitigate the worldwide scarcity, especially in arid regions. Salt-based composite materials are extensively used sorbents for SAWH, however, they suffer from complex preparation avoid salt leakage. Furthermore, significant amount of heat produced during process is often neglected and wasted. Herein, an integrated strategy developed synthesis salt-based stable super moisture-sorbent sponge by using chelation LiCl dopamine (DA), simultaneous polymerization DA on melamine (PMS). The as-prepared LiCl/PMS/CNTs showed high uptake, reaching 1.26 1.81 g

Enhancement of Water Productivity and Energy Efficiency in Sorption-based Atmospheric Water Harvesting Systems: From Material, Component to System Level

ACS Nano, Journal Year: 2024, Volume and Issue: 18(46), P. 31597 - 31631

Published: Nov. 5, 2024

To address the increasingly serious water scarcity across world, sorption-based atmospheric harvesting (SAWH) continues to attract attention among various production methods, due it being less dependent on climatic and geographical conditions. Water productivity energy efficiency are two most important evaluation indicators. Therefore, this review aims comprehensively systematically summarize discuss enhancement methods for SAWH systems based three levels, from material component system. First, level covers characteristics, categories, mechanisms of different sorbents. Second, focuses sorbent bed, regeneration energy, condenser. Third, system encompasses design, operation, synergetic effect generation with other mechanisms. Specifically, key promising improvement are: synthesizing composite sorbents high uptake, fast sorption kinetics, low (material level); improving thermal insulation between bed condenser, utilizing renewable or electrical heating desorption multistage design (component achieving continuous operation a desired number beds rotational structure, integrating Peltier cooling passive radiative technologies (system level). In addition, applications challenges explored, followed by potential outlooks future perspectives. Overall, is expected that article can provide directions guidelines aim efficiency.
