As global freshwater demand intensifies, conventional desalination faces mounting challenges from brine disposal and energy consumption. Now, researchers from Donghua University, led by Prof. Haoxuan Li and Prof. Meifang Zhu, have developed a mangrove leaf-inspired upward-hanging evaporator using 3D photothermal spacer fabric (PPSF). This novel design achieves zero-liquid-discharge (ZLD) desalination while maintaining high evaporation rates and enabling simultaneous salt recovery.

Why This Matters

Innovative Design

Performance Highlights

This work presents a paradigm shift in solar desalination—integrating biomimetic design, thermal management, and ZLD strategy—for sustainable freshwater and salt co-production.
