Sustainable solar water purification: Exploring the structural advantages of higher plants.

A higher plant-derived solar evaporator achieves an evaporation rate of 3.2 kg m -2 per hour under 1 sun, demonstrating high efficiency for water purification.

• Why it matters: Efficient and sustainable solar vapor generation systems are needed for practical water purification, but current developments face challenges in scalability and continuous outdoor use.
• What they did: The study introduced a plant-based evaporator using carbon black-coated wood slices, nanocellulose aerogel, and wheat straws, demonstrating continuous water collection outdoors with a daily yield of up to 10.9 kg m -2 under 0.5 to 0.9 sun.
• The result: This cost-effective, scalable device with high water purification efficiency advances the potential for real-world solar water purification applications using renewable raw materials.
