Solar-driven interfacial evaporation technology presents a promising approach for large-scale, sustainable water resource utilization, with significant potential in seawater desalination and wastewater treatment. However, the simultaneous removal of waterborne pollutants during solar remains challenge. This study introduces an all-natural photothermal hydrogel composed chitosan, cellulose nanofibers, carbonized spent bleaching earth (C@SBE) efficient heavy metal remediation. The performance was enhanced by optimizing its three-dimensional porous structure incorporating C@SBE to improve conversion efficiency adsorption capacity. Under one-sun irradiation, achieved impressive rate 2.17 kg m-2 h-1 90.8%, exhibiting excellent salt resistance long-term operational stability. Furthermore, demonstrated maximum Cu2+ capacity 145.3 mg/g, kinetics following pseudo-second-order model isotherms aligning Langmuir model. mechanism involved synergistic effects chitosan amino chelation, electrostatic interactions, ion exchange. Soil remediation experiments further revealed that effectively reduced concentrations contaminated soil from 500 45.6 mg/kg under while simultaneously promoting healthy wheat seed growth. highlights green, efficient, multifunctional hydrogel, offering novel technological platform theoretical foundation solar-driven purification environmental

Preparation of ZnIn₂S₄/MoS₂–SA Photocatalyst Gel for Wastewater Treatment: Photocatalytic Performance and Solar Interfacial Evaporation

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Апрель 2, 2025

With the rapid advancement of industrialization, wastewater pollution has become an increasingly severe environmental issue. The integration photocatalysis with solar interfacial evaporation technology, which leverages abundant and clean energy power, drawn growing attention as effective solutions to this problem. In study, MoS2 nanosheets low-dimensional controllable morphology were successfully grown on layered ZnIn2S4 using a simple template method, resulting in novel nanoflower heterojunction photocatalyst. This photocatalyst was then combined sodium alginate, aerogels fabricated through directional freezing technology. ZnIn2S4/MoS2 photocatalytic aerogel demonstrated excellent performance under visible light, efficiently degrading various pollutants such rhodamine B(RhB)(30 min, 99%), methyl orange(MO)(30 tetracycline(TC)(1h, 88%), other antibiotics dyes. Notably, degradation efficiency for tetracycline remained at 88% even after five cycles use, highlighting aerogel's strong reusability stability across different pollutants. Additionally, current composite exhibits rate up 1.984 kg m-2 h-1 photothermal conversion 95.5%. These results demonstrate that is promising candidate sustainable water treatment, broad applicability stable polluted environments.

Solar-driven photothermal conversion technologies have gotten much attention for addressing the global freshwater crisis and energy shortage. However, several challenges remain regarding applied materials with their single function, complex manufacturing process, high raw material cost. Herein, performance of low-cost lignin was improved by one-step hydroxymethyl modification up to 52.16% maximum efficiency modified (Lg1-OH). The enhancement mechanism Lg1-OH proposed structural analysis simulation calculations. First, a larger hydrogen bond network strengthens π-π stacking between benzene rings thus enhances lignin. Second, conjugation effect groups increases electron cloud density ring, ensuring more heat can be obtained exciting electrons under same solar power. Subsequently, gel (PG) successfully prepared using solar-driven thermoelectric production water purification. device (TED) power 20.85 W/m2 0.5 W/cm2 sun irradiation, evaporator reached superior evaporation rate 4.72 kg/(m2 h) 0.3 irradiation.
