Ultra‐Durable Solar‐Driven Seawater Electrolysis for Sustainable Hydrogen Production

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

Published: Oct. 12, 2024

Abstract Ions in seawater hinder direct sewage electrolysis due to the extreme corrosion of Cl − anode and reaction Mg 2+ Ca on cathode producing solid substances, which reduce electrolytic efficiency. However, traditional desalination consuming fossil fuel with massive CO 2 emissions threatens human survival. Therefore, zero‐carbon emission, ultra‐durable, large‐scale production freshwater from for water is urgently needed. Herein, a multifunctional system demonstrated based ultra‐durable solar outdoors. The evaporators reach an evaporation flux 1.88 kg m −2 h −1 photothermal conversion efficiency energy as high 91.3% excellent salt resistance even saturated saltwater Marangoni effects. Moreover, condensation pure reaches 0.54 L outdoors, suitable 20 cm × engineered electrode equipped Janus membrane powered by panel produce H ultrafast unidirectional transport bubbles enabled membranes can greatly improve at rate approaching 85 mL continuous 24

Self-Floating Polydopamine/Polystyrene Composite Porous Structure via a NaCl Template Method for Solar-Driven Interfacial Water Evaporation

Polymers, Journal Year: 2024, Volume and Issue: 16(15), P. 2231 - 2231

Published: Aug. 5, 2024

Solar energy, as a clean and renewable energy source, holds significant promise for addressing water shortages. Utilizing solar evaporation is seen an effective solution in this regard. While many existing interfacial photothermal systems rely on nanoparticles or graphene support materials, study introduced polydopamine (PDA) material due to its environmental friendliness excellent photon absorption characteristics that closely match the spectrum. Polystyrene (PS) was also porous structure density similar water, enabling it float water. The resulting PS-PDA composite evaporator exhibited conversion efficiency comparable (over 75%), yet with lower production costs minimal impact. This innovative approach offers scalable water-scarce regions, providing cost-effective efficient means address scarcity. use of PDA PS context highlights potential utilizing common materials novel ways meet pressing challenges.

Bio‐Inspired 3D Substrates for Efficient Interfacial Solar Steam Generation: FeNi Nanoparticles‐Coated Wood Sponge and Pine Cone for Sustainable Desalination

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(16)

Published: April 1, 2025

Abstract Interfacial solar steam generation (ISSG) is an emerging technology for sustainable water production, harnessing energy to desalinate seawater and treat wastewater. However, the development of efficient, cost‐effective photothermal materials these systems remains a challenge. This study investigates use FeNi nanoparticles (NPs) coated on bio‐inspired substrates—wood sponge (WS) pine cone (PC)—for ISSG. These substrates, enhanced their high porosity hydrophilicity, facilitate transport via capillary action, whereas NPs improve light absorption conversion. Results show that both PC/FeNi WS/FeNi demonstrate evaporation efficiencies, with outperforming in terms flux stability across multiple cycles. The PC‐based device achieved 1.73 kg m 2 h⁻¹ efficiency 97.59% under 1 sun illumination, showing promise large‐scale desalination. Furthermore, photoabsorbers effectively reduced ion concentrations seawater, meeting WHO drinking standards. highlights potential bio‐inspired, 3D structured substrates like PC efficient ISSG applications.
