Published: March 7, 2025

Environmental pollution and sewage surges necessitate effective water purification methods. Solar interfacial evaporation offers a promising solution, which needs advancements in salt resistance, efficiency, stability. Herein, inspired by the structure of wood, unidirectional freeze-drying method was used to develop vertically aligned channels antioil-fouling poly(vinyl alcohol)-CNTs-waste carton fiber@polydopamine (PVA-CNTs-WCF@PDA) aerogel for desalination wastewater treatment. The anisotropic three-dimensional porous enables it rapidly transport interface resist deposition. Meanwhile, its unique is combined with CNTs PDAs excellent broadband spectral absorption capacity because composite aerogels can interact molecules reduce their vaporization enthalpy. shows an photothermal rate (2.626 kg m-2 h-1) efficiency (94.24%) under one-sun irradiation. Additionally, evaporator conduct 10 consecutive evaporations 3.5% brine, indicating that has ability desalination. Finally, also purify oil-in-water emulsion mine wastewater. It be seen there are no obvious oil droplets treated treatment effect reaches 89.13%. showed application prospects field purification.

Published: Feb. 23, 2025

Abstract Solar‐driven interfacial water evaporation holds a broad application prospect in the domain of seawater desalination. However, traditional desalination technology is facing challenge large‐scale preparation and desalting performance. Herein, based on easy processing low cost advantages carbon‐based solar‐thermal materials, study proposes novel strategy to use surfactant Pluronic F127 encapsulate carbon black form size‐stable “core–shell” nanomicelle. Then, evaporator cross‐linked by nanomicelle polyvinyl alcohol constructed with surface patterned design inspired honeycomb structures, which proved that has excellent salt resistance Marangoni effect. Furthermore, it can be used generate electricity realize integration outdoor evaporating generation. The solar reach an rate 2.19 kg m −2 h −1 under one sunlight irradiation. area patterning 132 cm 2 (22 × 6 cm) output voltage natural light up 561 mV. Significantly, maintain persistent without accumulation during for 10 days. This work provides valuable perspective industrialization high‐performance evaporators.

Architecting of All-Cellulose-Based Wicking Fabric for a Large-Scale, Low-Cost, and Highly Efficient Solar Desalination Evaporator

ACS Nano, Journal Year: 2025, Volume and Issue: unknown

Published: March 1, 2025

Interfacial solar vapor generation (ISVG) technology has been considered a promising and sustainable strategy for seawater desalination wastewater treatment. However, its practical application is greatly limited due to severe salt accumulation poor long-term evaporation stability. Herein, an all-cellulose-based wicking fabric (CB@CA/CF) fabricated via breath figure template (BFT) method high-performance stable desalination. The abundant porous structure of carbon black@cellulose acetate (CB@CA) endows the evaporator with high light absorption (∼96.9%) rapid steam escape. hydrophilic CA network also changes hydration state reduces water enthalpy. More importantly, unique double-layer CB@CA cotton (CF) produces antigravitational effect, providing sufficient supply preventing on surface. As result, CB@CA/CF can achieve rates 2.08 kg m-2 h-1 in pure 1.98 3.5 wt % NaCl solution under one-sun irradiation, without any over 8 h. Moreover, designed floating system obtain freshwater collection 8.39 per day natural environmental conditions.
