Published: Feb. 16, 2025

Abstract Solar vapor generation (SVG) garners significant attention as a technology for producing clean water owing to its high efficiency and zero carbon emissions. However, the widespread adoption of SVG is constrained by cost, low mechanical strength, complex fabrication processes current photothermal materials. Lignin coal, abundant in aromatic rings, C═O bonds, quinone structures, present natural advantages enhancing light absorption improving properties This review begins with an overview fundamentals strategies aimed at promoting efficiency. It then delves into structural characteristics conversion mechanisms lignin highlighting their unique contributions field. Further, latest advancements application lignin/coal‐based materials are comprehensively summarized. work not only lays systematic scientific foundation development next‐generation but also underscores potential value‐added utilization thereby contributing sustainable resource management.

Abstract Solving the global challenge of freshwater scarcity is great significance for over one billion people in world. Solar water evaporation based on plasmonic nanostructures most promising technologies due to its high efficiency. However, efficiency this nanostructure‐based technology can hardly achieve 100%. Therefore, it highly desired develop new solar converters utilizing local heating and reasonable structure design break limit solar‐to‐vapor production. Here, a sponge developed as converter with excellent full‐solar‐spectrum absorption, good heat localization performance, fast kinetics through 3D nanostructures, achieving 131% Distinct from traditional 2D localized heating‐based nonmetallic evaporation, simultaneously efficient super large water–air interfaces boosting The be also used universal purifying seawater, metal ion solutions, organic pollutant strong acid alkaline solutions. efficiency, universality purification suggest that novel bring significant way alleviate crisis resources.

Constructing a Thin Layer of the Concentrated Polyelectrolyte Solution on the Hydrogel Surface That Can Considerably Improve the Solar Evaporation Efficiency

Macromolecules, Journal Year: 2024, Volume and Issue: 57(20), P. 9811 - 9822

Published: Oct. 10, 2024

Converting solar energy to evaporative obtain clean water has been intensively studied. However, the efficiency of reported evaporators remains limited, and their construction is complex challenging control. Here, we report a facile method for constructing efficient by utilizing thin-layer, highly concentrated polyelectrolyte solution as evaporation layer. Under an electric field, single layer polyelectrolyte–shelled micelles grafted onto hydrogel surface, controllably stably modifying chains on outermost surface. These chains, with low chemical potential, efficiently absorb form Theoretical calculations indicate that molecules in possess high hydrogen bonds between them are significantly disrupted, thus minimizing energy. Consequently, simulated seawater under 1 kW m–2 irradiation, as-prepared evaporator without photothermal component achieves rate 3.74 kg h–1 (1.5 times highest nonphotothermal hydrogels) particles β-Ti3O5 reaches record-breaking value (6.92 h–1). Remarkably, ion rejection ratio 99.97% due repulsion from positively charged polyelectrolyte.
