Besides, there is no significant change in evaporation performance after 21 cycles in the case of seawater treatment, suggesting that the designed 3D NA possess sustainable stability and self-cleaning function to restrain salt deposition. With highly efficient evaporation rate and long-term sustainable solar steam generation, such 3D NA can offer new strategy for desalination and sewage treatment. </p>
