Опубликована: Янв. 2, 2025

Abstract Interfacial solar evaporation offers a green and sustainable solution to solve clean water shortages via solar‐driven desalination. However, salt crystallization accumulation on evaporators have become the primary hindrances long‐term practical application of interfacial technology. To tackle this challenge, photothermal evaporator with novel parallel two‐water paths strategy is developed in study. Unlike conventional one‐way path, which generally leads at supply end surfaces, thereby limiting lifespan compromising performance, here, second ion diffusion distribution within reconfigured optimized. No occurs either surfaces or paths, eliminating impact performance enabling convenient collection. A high stable rate 3.09–3.26 kg m −2 h −1 recorded over 84 continuous NaCl (3.5 wt.%) without evaporator, making it an ideal for zero liquid discharge evaporation.

Abstract Using solar energy to drive seawater desalination via steam generation (SSG) is a sustainable strategy for clean water supply. The weak efficiency and poor durability due salt deposition severely restrict practical SSG operation. Traditional evaporators are difficult simultaneously guarantee efficient evaporation long‐term rejection increased salinity. Herein, tackle this dilemma, thermal gradient fabric (TGF) evaporator with an auxiliary active field constructed. Different from traditional works where additional resources improved rate exacerbate accumulation, the well integrated external boost ion circulation through moderate Marangoni flow, leading continuous superior utilization under high‐salinity desalination. accelerated (2.42 kg m −2 h −1 ) resistance (30 days of in 10 wt.% brine) achieved optimized construction. An outstanding collection (5.84 observed during outdoor desalination, which proves purification ability. This study provides new insight into construction fields production, believed.

Solution-processable polymer membranes with hydrophilic subnanometre pores for sustainable lithium extraction

Nature Water, Год журнала: 2025, Номер 3(3), С. 319 - 333

Опубликована: Март 12, 2025

Abstract Membrane-based separation processes hold great promise for sustainable extraction of lithium from brines the rapidly expanding electric vehicle industry and renewable energy storage. However, it remains challenging to develop high-selectivity membranes that can be upscaled industrial processes. Here we report solution-processable polymer with subnanometre pores excellent ion selectivity in electrodialysis extraction. Polymers intrinsic microporosity incorporated hydrophilic functional groups enable fast transport monovalent alkali cations (Li + , Na K ) while rejecting relatively larger divalent ions such as Mg 2+ . The surpasses performance most existing membrane materials. Furthermore, were scaled up integrated into an stack, demonstrating simulated salt-lake brines. This work will inspire development selective a wide range critical resource recovery global circular economy.

Solar-driven interfacial evaporation technologies for food, energy and water

Опубликована: Янв. 15, 2025

Solar-driven interfacial evaporation technologies use solar energy to heat materials that drive water evaporation. These are versatile and do not require electricity, which enables their potential application across the food, nexus. In this Review, we assess of solar-driven in clean-water production, wastewater treatment, resource recovery. Interfacial can produce up 5.3 l m–2 h−1 drinking using sunlight as source. Systems designed for food production coastal regions desalinate irrigate crops or wash contaminated soils. Technologies being developed simultaneously both clean through have reached 204 W electricity 2.5 h–1 separate systems. Other approaches combinations could potentially full spectrum generate multiple products (such water, heating cooling, and/or fuels). future, aid provision low-resource rural settings lack reliable access these essentials, but systems must first undergo rigorous, scaled-up field testing understand performance, stability competitiveness. This Review discusses manage wastewater, recover resources energy.
