Delivering sufficient water to the evaporation surface/interface is one of most widely adopted strategies overcome salt accumulation in solar-driven interfacial desalination. However, transport and heat conduction loss are positively correlated, resulting trade-off between thermal localization resistance. Herein, a 3D hydrogel evaporator with vertical radiant vessels prepared surmount long-standing trade-off, thereby achieving high-rate stable solar desalination high-salinity. Experiments numerical simulations reveal that unique hierarchical structure, which consists large vessel channel, vessels, porous walls, facilitates strong self-salt-discharge low longitudinal conductivity. With structure employed, groundbreaking comprehensive performance, under sun illumination, rate as high 3.53 kg m-2 h-1 , salinity 20 wt%, continuous 8 h achieved, thought be best reported result from salt-free system. This work showcases preparation method novel microstructure, also provides pivotal insights into design next-generation evaporators high-efficiency tolerance.
