Photothermal-responsive tungsten bronze/recycled cellulose triacetate porous fiber membranes for efficient light-driven interfacial water evaporation

CoWO4–x-Based Photothermal Membranes for Solar-Driven Water Evaporation and Eutrophic Lake Water Purification

“…Meanwhile, we also find that the surface of NF has a certain roughness, and its thickness is about 300 μm (Figure S5a–c). CoWO 4– x was deposited onto the NF surface using a pouring method because it was simpler and more efficient compared to other methods such as freeze-drying, vacuum filtration, molten salt, and electrospinning, thus making it an unparalleled advantage in actual large-scale production. − From the SEM images of CoWO 4– x @NF at different magnifications, we can observe that its pore diameter (∼240 μm, Figure S4b) is slightly reduced after CoWO 4– x deposition and the 3D skeleton of NF is well retained (Figure d–f). In comparison, CoWO 4– x @NF has a relatively smooth surface, and there are some cracks on the surface because of the evaporation of ethanol.…”

Advances and challenges of broadband solar absorbers for efficient solar steam generation

“…When the LSPR energy is higher than the band gap due to the adequate self-doping density, the interband plasmon resonances occur, allowing the emergence of much more hot carriers in TiO 1.67 NPs for efficient light harvesting and heat generation. 90,91 In addition to the oxygen-deficient metal oxides, some other doped metal oxides, such as rubidium tungsten bronze (Rb x WO 3 ), 92 hydrogenated metal oxide (H 1.68 MoO 3 ), 93 and defective HNb 3 O 8 , 94 also exhibit quasi-metallic properties and excellent light absorption and photothermal conversion capabilities, providing the possibilities for application in solar evaporation.…”

Scalable Fabrication of Conjugated Microporous Polymer Sponges for Efficient Solar Steam Generation

“…To enhance the efficiency of solar-thermal conversion, materials with high light-absorption capacity and high conversion capability are required. Over the past 10 years, different kinds of metal materials − and carbon materials − have been developed as water evaporators based on the principles of solar-thermal conversion. Metal-based materials exhibit the strong absorption of near-infrared (NIR) light due to the effect of surface plasmon resonance. , Especially, plasmonic metals such as Au and Ag have been proved to be the most effective materials for solar-thermal conversion.…”
