“…15h(ii)). 247 Hou et al developed a vanadium oxide-based thin film for solar steam generation and disinfection by assisting haloperoxidase catalyze. Findings exhibit that in the presence of H 2 O 2 , oxygen-rich V 6 O 13 prompts conversion of Br − to HbrO, leading to inactivate E.coli as the results of acidic activity of HbrO.…”

“…Freshwater scarcity remains a major global challenge, due to global population growth, industry development, and climate change. − Considering the abundant seawater and solar energy resources, solar-driven seawater desalination is one of the most effective approaches to boost freshwater supply. Compared with the traditional desalination technologies, solar steam generation (SSG) attracted much more attention owing to its eco-friendly nature, low cost, and high efficiency. − The ideal SSG system always possesses broadband light absorption, lower thermal conductivity, and timely water transportation. − The photothermal materials can locate the widely absorbed solar energy onto the upper surface and reduce energy loss to the surrounding environment, thus converting most of the absorbed energy into heat to generate steam. − Therefore, compared with previous reports, VOCs and thermal management are more and more concerned by researchers. − The development of low-cost and efficient SSG systems is still in great need for favorable economic and social benefits.…”

Solar steam generation (SSG) is an effective way to mitigate the freshwater crisis. However, challenges still remain in scalable preparation, cost-effectiveness, and expanding the scope of practical applications for photothermal materials. Herein, a biomass-based solar steam generator (named OR-INP) with salt-resistant, oil-repellent, and anti-fouling performances is fabricated by grafting poly(ionic liquid)s onto celluloses from waste newspapers and then conducting oil-repellent modification. Benefiting from the broad solar absorption in the wet state (ca. 92%), low thermal conductivity (0.1108 W m–1 K–1), and strong hydrophilic and oleophobic properties, the solar evaporation efficiency is as high as 93.25% for pure water, 84.96% for 20 wt % NaCl, and 78.46% for 5 wt % oily wastewater, under 1 sun irradiation. Moreover, the aerogel still has excellent purification effects on solutions which contain organic dyes, heavy metal ions, or bacteria. Therefore, combining the merits of salt resistance, oil repellency, and wastewater treatment, this work develops the prospect of employing waste biomass resource-based photothermal materials and expands the practical application range of biomass-based evaporators.

Solar-driven water evaporation is essential to provide sustainable and ecofriendly sources of fresh water. However, there are still great challenges in preparing materials with broadband light absorption for high photothermal efficiency as well as in designing devices with large evaporation areas and small heat dissipation areas to boost the water evaporation rate. We designed a hanging-mode solar evaporator based on the polyaniline/carbon nanotube (PANI/CNT) fabric, in which the photothermal fabric acts as the solar evaporator and the micropores on the cotton fabric act as the water transfer channels. The hanging mode provides efficient evaporation at both interfaces by greatly reducing the heat dissipation area. The hanging mode PANI/CNT fabric solar evaporator can achieve an evaporation rate of 2.81 kg•m −2 •h −1 and a photothermal efficiency of 91.74% under a solar illumination of 1 kW•m −2 . This high-performance evaporator is designed by regulating the photothermal material and evaporation device, which provides a novel strategy for sustainable desalination.
