A Robust Solar Evaporator with Hierarchical Architecture for Ultrahigh Efficiency and Large-Scale Zero-Liquid-Discharge Desalination.

ABSTRACT: Solar-driven desalination offers a green and sustainable strategy for solving the issue of freshwater scarcity. However, it remains a challenge to develop a robust evaporator via an eco-friendly strategy, capable of resolving the long-standing trade-off between the water supply, salt accumulation, and thermal localization. Herein, a hierarchical solar-absorbing architecture derived from mycelium is developed for high-performance desalination. With the merits of multi-level spatially low-tortuosity channels, gradient wettability and directional transport, the evaporator achieves an impressive evaporation rate (up to 10.25 kg m^-2 h^-1 for 25 wt.% brine), efficient salt collection (1.95 kg m^-2 h^-1 for 25 wt.% brine), zero liquid discharge desalinatio
