Solar-driven desalination technology is currently an important way to obtain freshwater resources. Significantly, porous materials are used as substrate of interface solar evaporator, and their specific impact water transport property thermal management during evaporation worth exploring. In this paper, poly(vinyl alcohol) (PVA) sponges were prepared by a chemical foaming method, adjusted the PVA polymerization degree, formaldehyde-hydroxyl ratio regulate pore size, polypyrrole (PPy) was grown in situ on surface skeleton sponge construct new interfacial evaporator (PPy/PVA) with different structures. As size changes, trends capability opposite. Among them, PPy/PVA-3 achieves temperature 38.9 °C rate 1.764 kg m-2 h-1 under 1 Sun light. And efficiency exceeds theoretical limit (100%). This because it has optimal structure balance competition mechanism between two aspects. At same time, exhibits good cyclability, stability, self-cleaning capability. addition, practical applicability purification both organic dyes seawater.

Salt deposition is a disturbing problem that limits the development of passive solar-driven interfacial evaporation. Inspired by fluid control mechanism Tesla valve, novel solar evaporator proposed with valve-like water transport structure to prevent salt accumulation at evaporation interface. A unique "ion diode" resistance this significantly achieved optimizing two asymmetric structures, consisting one side and wide-leg side, which establish reverse-suppressing forward-accelerating channel. In contrast limited ion migration typical symmetric evaporator, such channel caused water/salt ions difference between supply reinforces on thus leading an apparent unidirectional from bulk through side. Consequently, rate 3.25 kg m

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.

Abstract The escalating global resource and environmental crisis has intensified the urgent demand for efficiently extracting freshwater critical metals from contaminated water sources, particularly nuclear‐contaminated seawater. Herein, a biomass‐based solar‐powered hierarchical self‐extraction micro‐network (BSSM) is proposed presented, an innovative system that seamlessly integrates solar‐driven generation with highly selective cesium ion (Cs + ) extraction. A bamboo‐derived biochar surface‐loaded cobalt oxide nanoparticles (CoO NPs) prepared utilized to comprehensively validate BSSM's efficacy. Leveraging hierarchically engineered microenvironments authigenic multi‐field synergies, designed BSSM achieves high production rate of 3.3 kg m −2 day −1 impressive Cs extraction capacity 34.58 mg g . In conclusion, this study establishes transformative paradigm recovery, providing scalable eco‐friendly panacea address pressing issues, including scarcity, nuclear pollution, security.
