外文摘要：Harvesting solar energy for seawater desalination and wastewater purification has emerged as a promising approach to produce clean water, but simultaneously realizing superior light absorption, heat management, salt resistance, and durability in a solar evaporator remains challenging. Here, inspired by lotus seedpod, a 3D spacer fabric decorated with multiwalled carbon nanotubes (MWCNTs) and polyaniline (PANI) was successfully fabricated and served as a standalone solar evaporator. Therein, the upper honeycomb-like porous architecture expands the effective surface area for solar harvesting, and then synergistically cooperates with MWCNTs and PANI to achieve a high light absorption of 97.17%. The bottom planar knitted surface directly contacts with water, and ensures rapid water transport through water-wicking effect and capillary force of microchannels. While the mid-interconnected spacer yarns not only decouple the photothermal evaporation layer from bulk water to minimize conduction heat loss, but also facilitate the swift water transport and automatic ions reflux, thereby effectively mitigating salt accumulation on fabric surface. Under 1 sun illumination, this evaporator achieves a high evaporation rate of 1.75 kg & sdot;m- 2 & sdot;h- 1 with an efficiency over 96%. Meanwhile, it can also maintain efficient and durable evaporation performance even during long-term seawater desalination. The inorganic heavy metal ions and organic dyes in wastewater can be greatly removed after purification, with the removal efficiency exceeding 99.9%. This study provides a new perspective to design high-performance solar evaporator for efficient water desalination and purification.
