A versatile platform of poly(acrylic acid) cryogel for highly efficient photothermal water evaporation

Abstract

Photothermal water evaporation, benefiting from solar energy, is one hot topic concerning with seawater desalination, sewage treatment and water recovery. Commonly, photothermal evaporation system consists of photothermal material supported by...

A cryogel solar vapor generator with rapid water replenishment and high intermediate water content for seawater desalination

“…As a result of the differences in T g , PVA hydrogels have relatively smaller internal pores (∼5–20 μm) compared with PHEA- (∼90–110 μm) and PPEG-based cryogels (∼70–130 μm) (Table S1†). This result is in good agreement with the pore size properties of hydrogels 32,50,51 and cryogels 52–54 reported in previous literature. Increasing the solid content of the polymer network usually leads to enhanced mechanical properties.…”

A Comprehensive Review on Adsorption, Photocatalytic and Chemical Degradation of Dyes and Nitro-Compounds over Different Kinds of Porous and Composite Materials

“…Their adsorption efficiency is not bad and quite satisfactory, but faster adsorption rate is required in this computerized world.On the other hand, cryogels are the most important candidate for removing dyes and will be useful in wastewater treatment over conventional polymeric hydrogels. Cryogels have macroporous structures due to their synthetic route (cryogenic conditions), making these materials more suitable for different applications already studied by our group and other researchers [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 ], as if the materials have a better adsorption capacity but a closed cavity, they will not be considered a suitable candidate for adsorption studies due to their long duration of adsorption. Cryogels have a pore size in the 50–200 um range, facilitating dyes’ fast diffusion and adsorption.…”

A Multifunctional tannic acid–Fe3+–graphene oxide loaded alginate photothermal network: an interfacial water evaporator, a disinfector and a power generator

“…Engineered nanostructures may promote maximum light absorption and heat conversion. 3 Inorganic metallic nanoparticles, 4 semiconductors, 5 carbon derivatives, 6 organic polymers, 7 and 2D transition metal carbide/nitride based hybrids 8 are examples of such nanostructures. From those photothermal materials graphene oxide (GO) comprises a 2D layer structure which consists of stacked hexagonally arranged carbon atoms and has been shown to have good photothermal properties.…”
