A solar-powered interfacial evaporation system based on MoS₂-decorated magnetic phase-change microcapsules for sustainable seawater desalination

Abstract

A novel solar-powered interfacial evaporator based on the MoS2-decorated magnetic phase change microcapsules (hereafter named "MoS2-MEPCM") has been developed for sustainable seawater desalination. The MoS2-MEPCM was synthesized through encapsulating n-docosane...

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

“…[1][2][3][4] Currently, solar-driven interfacial desalination has emerged as a promising technique to increase potable water supplies due to the abundant and sustainable solar energy. [5][6][7][8] Over the past decades, evaporation performance has been optimized by improving optical absorption, [9][10][11][12][13][14] minimizing heat loss, 15 reducing the evaporation enthalpy, 16,17 latent heat utilization [18][19][20] as well as quick water collection. [21][22][23] Unfortunately, salt deposits emerge at the evaporating surface in longterm desalination, particularly for high-salinity brine, causing reduced light absorption and inefficient water transport.…”

Enhanced Photothermal Effect Assisted by Resonance Energy Transfer in Carbon/Covellite Core–Shell Nanoparticles toward a High-Performance Interfacial Water Evaporation Process

“…To date, various core–shell structured photothermal materials have been extensively investigated for several applications such as phase-change materials, antibacterial agents, and tumor therapies . A few recent studies on interfacial evaporators, based on magnetic phase-change microcapsules, where the phase-change material as a core is enveloped by a solar absorber-coated magnetic composite shell, have further underscored the potential of core–shell heterostructures in enhancing photothermal effects. – Nevertheless, the exploitation of the improved photothermal effect originating from the core–shell structure to facilitate the interfacial water evaporation process has yet to be fully examined. In addition, the mechanism driving the elevated heat generation in the core–shell structure has seldom been studied.…”
