Rational Design of a High Performance and Robust Solar Evaporator via 3D‐Printing Technology (Adv. Mater. 38/2021)

Abstract

Solar Evaporators In article number 2102649, Ji‐Hyun Jang and co‐workers present a 3D‐printed solar evaporator that can efficiently utilize solar energy (99%) with an evaporation rate of 1.60 kg m−2 h−1 and efficiency of 89% under 1 sun irradiation, which promotes light‐harvesting capacity via multiple reflections on the surface and provides competitive benefits for preventing deposition of salt while quickly pumping the water, for long‐term provision of drinking water in remote locations.

“…Moreover, the evaporation enhancement is also attributed to the harvesting of ambient energy (Figure S35, Supporting Information). As shown in Figure 6d and Table S6 (Supporting information), the evaporation performances of the 3D AGA IV are superior to those of recently reported solar generation systems [17,18,[23][24][25]31,[33][34][35][36][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109][110][111][112] under a wide salinity brine (3.5-25 wt%). To investigate the no salt deposition and salt collection behavior of the p-MF-equipped 3D AGA IV when treating the high-salinity brine, a continuous 36 h desalination test was performed in 20 wt.% brine under one sun illumination.…”

Nature-inspired sustainable solar evaporators for seawater desalination

“…However, with 3D printing, many complex structures can be achieved by creating models. 101,102 Inspired by bird beaks and Nepenthes alata, Song et al used 3D printing to prepare a tapered and surface-loaded grooved structure that allows salt to crystallize directionally at the top (Fig. 11A, a-c).…”

Water bridge solar evaporator with salt-resistance and heat localization for efficient desalination

“…A slight decrease of the evaporation rates in 15 wt% brine (1.57 kg m −2 h −1 ) and 20 wt% brine (1.56 kg m −2 h −1 ) is observed compared with that in 3.5 wt% brine (1.64 kg m −2 h −1 ), which is attributed to the decreased vapor pressure of high-salinity brine. 52,53 It is worthwhile to mention that compared with the state-of-the-art salt-free solar evaporators, such as hydrophobic surface modication evaporator, 31,40,54,55 porous structure for ion back diffusion 48,[56][57][58] and conned water layer strategy, 33,34,59 the WB 1.3-46-1.0 SE displays a comparable evaporation rate in low-salinity brine (0-3.5 wt%). However, the WB 1.3-46-1.0 SE exhibits a high evaporation rate of 1.56 kg m −2 h −1 in high-salinity brine (20 wt%), which is superior to previously reported evaporators with an evaporation rate below 1.45 kg m −2 h −1 (Fig.…”
