Integrated Solar Evaporator with Salt Resistance and Lipophobicity Derived from Waste Newspapers for Efficient Desalination

ACS Sustainable Chemistry & Engineering, Journal Year: 2023, Volume and Issue: 11(6), P. 2586 - 2598

Published: Feb. 2, 2023

Solar steam generation (SSG) is an effective way to mitigate the freshwater crisis. However, challenges still remain in scalable preparation, cost-effectiveness, and expanding scope of practical applications for photothermal materials. Herein, a biomass-based solar generator (named OR-INP) with salt-resistant, oil-repellent, anti-fouling performances fabricated by grafting poly(ionic liquid)s onto celluloses from waste newspapers then conducting oil-repellent modification. Benefiting broad absorption wet state (ca. 92%), low thermal conductivity (0.1108 W m–1 K–1), strong hydrophilic oleophobic properties, evaporation efficiency as high 93.25% pure water, 84.96% 20 wt % NaCl, 78.46% 5 oily wastewater, under 1 sun irradiation. Moreover, aerogel has excellent purification effects on solutions which contain organic dyes, heavy metal ions, or bacteria. Therefore, combining merits salt resistance, oil repellency, wastewater treatment, this work develops prospect employing biomass resource-based materials expands application range evaporators.

Biopolymer-Based Hydrogels for Harvesting Water from Humid Air: A Review

Sustainability, Journal Year: 2023, Volume and Issue: 15(1), P. 848 - 848

Published: Jan. 3, 2023

Despite the shrinkage of water availability worldwide, demand has been climbing due to rapidly increasing human population and impacts numerous hydroclimatic factors. To feed growing meet with exigent need for freshwater, new sources must be identified utilized. In recent years, biopolymer-based hydrogels have explored as a sustainable inexpensive solution capture moisture from humid air supply. This review summarizes advances in preparation atmospheric harvesting that are synthesized based on cellulose, chitosan, and/or other biopolymers, well their agricultural applications. The properties performance different discussed compared. Since agriculture accounts more than 70% consumption, developing cost-effective hydrogel-based harvesting/supply system could promising relieving elevating stress arid semi-arid regions.
