Solar Water Purification: High‐Yield and Low‐Cost Solar Water Purification via Hydrogel‐Based Membrane Distillation (Adv. Funct. Mater. 19/2021)

In article number 2101036, Fei Zhao, Chenyang Zhao, Guihua Yu, and co-workers develop a hydrogel-based ultrathin membrane (HUM) for solar water purification. The HUM can synergistically coordinate facilitated vapor transfer and environmental energy harvesting in a solar-driven membrane distillation system, leading to a significant water yield improvement under one sun without any energy recycling and cooling accessories.
