Multiscale Synergistic Radial‐Fin Sponges With Activated Sidewall Evaporation Unlock High‐Efficiency Solar‐Driven ZeroLiquid Discharge
Interfacial solar evaporation is promising for hypersaline brine treatment, yet conventional 3D evaporators suffer from insufficiently activated sidewall evaporation and salt accumulation, preventing efficient and stable evaporation. Herein, we report a 3D open radial‐fin sponge (RFS) evaporator that addresses this...
