Abstract Polyoxometalates (POMs) display great potential for application in the photothermal field. However, high water‐solubility of POMs restricts their use solar‐driven interfacial evaporation. Therefore, controlling stability and fully utilizing characteristics is a challenge. Hence, strategy proposed through confining with single‐walled carbon nanotubes (SWCNTs), which serve as layer metal‐organic frameworks‐modified wood evaporator solar steam generation. are effectively protected by SWCNTs, concurrently narrow bandgap SWCNTs to increase light absorption. Furthermore, molecular dynamics simulations indicate that frameworks substrate can lower enthalpy evaporation regulating microenvironment hydrogen bonds. With this ingenious design, rate reaches 2.53 kg m −2 h −1 under 1 sun, exceeds most wood‐based evaporators. Meanwhile, also exhibits good purification performance seawater wastewater. This work provides precise regulation from level, be extended create more efficient

Porous and Salt-Tolerant Polyelectrolyte Hydrogels for Excellent Solar Evaporation

Industrial & Engineering Chemistry Research, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Hydrogels with a low evaporation enthalpy and high water-molecule activation capability are regarded as promising substrate materials for solar-driven interfacial evaporation. However, the uncontrollable porous channels cross-linking degree of traditional hydrogels limit water mass transportation, light absorption sites, salt reflux therefore result in efficiency, poor tolerance, terrible operational stability. Herein, we report poly(vinyl alcohol)/carbon nanotubes-co-poly(acrylic acid)-co-poly dimethyl diallyl ammonium chloride (PVA/CNTs-co-PAA-co-PDADMAC) (PADM) polyelectrolyte via chemical polymerizing strategy. The as-prepared possess interconnected (abundant porosity 76.24%, total pore area 0.99 m2 g–1, large average diameter 18.79 μm) controllable (good mechanical property), which can greatly promote transportation (0.395 g min–1), reflux. As result, PADM maintain rate 3.58 kg m–2 h–1, excellent tolerance (evaporation 3.18 h–1 under 20 wt % high-concentration brine), superior stability (invariable after 8 days continuous evaporation), exhibits great advantage

Decoration of Two‐Dimensional Cus Nanoflakes on Graphitic Carbon Foam Derived from Waste Plastic for Interfacial Solar Desalination

Solar RRL, Год журнала: 2025, Номер unknown

Опубликована: Март 10, 2025

Interfacial solar desalination using plasmonic metal semiconductors is a valuable process for freshwater production. However, the design of sustainable and efficient photothermal evaporator still challenging. In present research, polyethylene terephthalate waste bottles were upcycled into carbon foam (CF) further functionalized with CuS nanoflakes as layer. Analytical characterizations (X‐ray diffraction, Fourier transform infrared spectroscopy, Scanning electron microscopy, scanning transmission microscopy–high‐angle annular dark field) demonstrated successful decoration two‐dimensional Covellite on graphitic CF having microporous channels. UV/vis spectroscopy measurements show enhanced optical absorption CuS/CF up to 95% compared bare (72%). The experiment displayed an improved evaporation rate 1.90 kg m −2 h −1 CuS–CF 1.58 1.41 1 , reveling excellent water efficiency 91%. obtained results suggested that CuS‐functionalized derived from plastic useful strategy produce fresh upcycling materials good example circular economy through development engineered composite systems.

Solar interfacial evaporation (SIE) has emerged as a highly promising approach for sustainable freshwater harvesting. However, maintaining stable rate and achieving high yield in high-salinity brines remain significant challenge. In this study, we present the development of silicone sponge-based evaporators with "free-salt" structure, designed to enhance efficiency SIE collection. These evaporators, designated PSS@Fe
