Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 17(1)

Published: Sept. 27, 2024

Abstract Low-electrode capacitive deionization (FCDI) is an emerging desalination technology with great potential for removal and/or recycling ions from a range of waters. However, it still suffers inefficient charge transfer and ion transport kinetics due to weak turbulence low electric intensity in flow electrodes, both restricted by the current collectors. Herein, new tip-array collector (designated as T-CC) was developed replace conventional planar collectors, which intensifies significantly. The effects tip arrays on fields were studied computational simulations electrochemical impedance spectroscopy, revealed reduction barrier, barrier internal resistance. With voltage increased 1.0 1.5 2.0 V, T-CC-based FCDI system (T-FCDI) exhibited average salt rates (ASRR) 0.18, 0.50, 0.89 μmol cm −2 min −1 , respectively, are 1.82, 2.65, 2.48 folds higher than that serpentine 1.48, 1.67, 1.49 Meanwhile, solid content electrodes 1 5 wt%, ASRR T-FCDI 0.29 0.50 1.70 1.67 Additionally, efficiency 99.89% achieved remained above 95% after 24 h operation, thus showing its superior long-term stability.

Nanocellulose‐Based Interfacial Solar Evaporator: Integrating Sustainable Materials and Micro‐/Nano‐Architectures for Solar Desalination

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

Published: Nov. 17, 2024

Abstract Clean‐water harvesting through solar interfacial evaporation technology has recently emerged as a strategy for resolving global water scarcity. In this study, rapid carbon‐dioxide‐laser‐induced carbonization and facile ice‐templating is employed to construct cellulose‐based evaporator bearing hybrid multi‐layer micro‐/nano‐architecture (i.e., laser‐induced carbon (LC) nanostructure cellulose aerogel (CA) nano/microstructure). The LC exhibits light‐absorbing/photothermal nanoporous structure that offers high light absorption multiple scattering. Additionally, the CA numerous nanopores unidirectional microchannels facilitate transport via capillary action. This LC/CA enabled vapor generation with an average rate (ν) of 1.62 kg m −2 h −1 efficiency (η) 66.6%. To further enhance performance, polydimethylsiloxane (PDMS) layer coated onto side increase its floatability in simulated water; ν η PDMS‐coated (LC/CA/PDMS) increased 1.9 83.8%, respectively. LC/CA/PDMS exhibited value 1.68 seawater, originating from excellent resistance salt accumulation self‐cleaning ability. Furthermore, scalability fabrication well biodegradable properties.
