A photothermal and Fenton active MOF-based membrane for high-efficiency solar water evaporation and clean water production

Abstract

Solar-driven interfacial water evaporation (SDIWE) is a promising way to reduce the fresh water scarcity. However, it is still challenged to generate clean water from volatile organic compounds (VOCs) contaminated...

Solar-driven interfacial evaporation for water treatment: advanced research progress and challenges

“…Therefore, it is difficult to purify VOC-containing wastewater by SDIE. Ma et al 213 designed a PM (ZSG) with high Fenton catalytic activity. The high Fenton catalytic activity of ZSG promoted the generation of -OH, which degrades substances such as phenol of volatile organic solvents in situ, thereby helping to obtain clean fresh water.…”

MOF supraparticles for atmosphere water harvesting at low humidity

“…2,3 Current technologies used in water puri-cation mainly depend on other water resources or expensive infrastructure, i.e., desalination, wastewater treatment and multi-stage ash distillation, and it is impractical to apply these technologies to produce clean water in desert areas. [4][5][6] In this regard, sorbent-based atmospheric water harvesting (AWH) exhibits great potential to provide potable water, as about 13 sextillion (10 21 ) L of water exists in air at any given time through the hydrological cycle. 3 Sorbent materials can spontaneously adsorb water and release it when energy is supplied.…”

Removal of Typical Volatile Organic Compounds in Condensed Freshwater by Activated Persulfate during Interfacial Solar Distillation

“…At present, the control of VOCs entering into condensed freshwater was achieved by photocatalysis, , additional oxidants, − and membrane interception in the interfacial solar distillation process. For example, Song et al reported a dual-scale porous, photothermal/photocatalytic, flexible membrane for preventing VOCs from entering into the condensed freshwater during solar distillation; Shi et al reported the multifunctional honeycomb ceramic plates for the degradation of VOCs through the photo-Fenton reaction.…”
