Elucidating differences in solar-driven interfacial evaporation between open and closed systems

Solar-driven pH-responsive oil–water separation membranes for effective oil–water emulsion separation

“…The test room temperature was 27 1C, and the relative humidity was 50%. 40 As shown in Fig. 9(d-f), the surface temperature of PP-PPy 1 -pHR increases to 98.1 1C within 10 min, and the surface The water evaporation properties of the composite film were further investigated using simulated sunlight and the mass changes were recorded using an electronic mass balance.…”

Advanced nanostructured materials in solar interfacial steam generation and desalination against pathogens: combatting microbial-contaminants in water – a critical review

“…In contrast to solar stills, nanomaterial in solar interfacial steam generators used in a broad range from zero to three dimensional materials (including 2.5D) such as core-shell, nanospheres, nanorods, nanosheets, and monolithic structures. 61,157,158 In recent years various types of materials including carbon families such as carbon dots, 159 CNTs, 160,161 graphene, 162,163 reduced graphene oxide, graphite foam, carbon black, carbon fabrics, carbon foam; 74,164 semiconductor families such as copper sulphides, copper phosphate, titanium-based semiconductors, 53 hybrid (polymer-biomass-metal) structures 165,166 and noble metal family including gold, silver and palladium have been extensively used as high efficient photothermal materials in solar steam generators. Notably, combining nanomaterial with hydrogels, aerogels and polymer structures further boosted the performance of structure.…”

Cost-Effective and Scalable Solar Interface Evaporators Derived from Industry Waste for Efficient Solar Steam Generation

“…Recently, more remarkable photothermal materials with advanced composition or distinctive structure have been designed, showing exceptional photothermal conversion performance and high salt tolerance. 18,36,37 However, the high cost of most materials and complex manufacturing processes hinder their competitiveness compared with those of commercial desalination approaches. These problems can be addressed using polymeric photothermal materials, which are promising candidates due to their tunable properties and structure and easy and diverse fabrication methods.…”

“…The key to achieving high solar evaporation performance is the design and synthesis of ideal photothermal materials that enable rapid water transportation to the evaporation interface, high light absorptivity, and low thermal conductivity, confining most heat energy to the interface for fast evaporation. − A series of photothermal materials combing these key parameters have been studied, such as plasmonic metal, , carbon materials, − porous polymers, , biomass materials, , and hydrogels, − which show efficient water evaporation ability. Recently, more remarkable photothermal materials with advanced composition or distinctive structure have been designed, showing exceptional photothermal conversion performance and high salt tolerance. ,, However, the high cost of most materials and complex manufacturing processes hinder their competitiveness compared with those of commercial desalination approaches. These problems can be addressed using polymeric photothermal materials, which are promising candidates due to their tunable properties and structure and easy and diverse fabrication methods. − The obstacles to its industrialization application are its fragile pore structures and relatively high cost.…”
