“…It showed that CAEP‐PFO had super solar absorption capacity. Through comparison and searching data, it was found that the absorption efficiency of similar material without surface carbonization of wood fiber can only reach about 30 %∼50 %, [32–34] which might be attributed to the surface of CAEP‐PFO was graphitized after carbonization, resulting in a wider range of light absorption. The relationship between mass and temperature variation of the CAEP and CAEP‐PFO was studied by thermogravimetric analysis (TGA).…”

Solar steam generation (SSG) has become a cutting-edge technology to solve fresh water shortage. Herein, a neotype photothermal conversion material (CAEP-PFO) was designed and prepared by using expanded perlite as raw material and sodium alginate as crosslinking agent, through directional freezing, surface carbonization and oil-phobic modification. Through characterization analysis, the results showed that the prepared CAEP-PFO has a porosity of 92 %, a light absorption of more than 88 %, and a low thermal conductivity of 0.06834 W m À 1 K À 1 . In addition, CAEP-PFO exhibits excellent salt resistance and oil repellency, and possess an evaporation efficiency of 78.6 % in 10 % brine and 80.2 % in oil-bearing wastewater under the irradiation of 1 kW m À 2 , respectively. After 8 cycles of test, the evaporation efficiency in pure water is relatively stable, and the average evaporation efficiency can reach 84.28 %. The research may lay a foundation for the future preparation of photothermal materials and the practical application in seawater and oil-bearing wastewater.

“…The rich porous microstructures inside carbonized durian provide excellent capillary effect for sufficient water supply. Duan and Wang et al [ 14 ] prepared a wood‐based evaporator and studied the influence of the geometric characteristics of evaporator on its evaporation performance. Ling et al [ 10 ] analyzed the water transport and evaporation performance of evaporators based on corn cobs.…”

The floating porous structure consists of an optical absorption layer, a porous layer, and an insulating layer. Water is pumped through a porous structure to the top absorption surface for evaporation. A numerical model of interfacial evaporation of floating porous structure is established. A multiphysical field coupling model for heat transfer, flow, and mass transfer within porous structures is simulated. The transient temperature response, evaporation flux, and vapor concentration distribution inside the structure are calculated. Effects of porous structure characteristics, such as size and porosity, on evaporation performance are discussed. With the increase of structure radius, the evaporation amount increases gradually, but the evaporation per unit area decreases with the radius. With the increase of the structure height, the evaporation amount and the evaporation flux decrease, but the decrease is relatively small. The porosity of the porous layer ε1 has a significant effect on the evaporation performance. The increase of ε1 is beneficial to the evaporation of water. When ε1 < 0.3, the effect of the porosity of insulation layer ε2 on the evaporation performance can be neglected.
