Solar-driven interfacial evaporation has been regarded as a promising method to alleviate water shortage. However, the organic contaminants are commonly accumulated on the evaporator during the evaporation process, which not only reduces the service life of the evaporator but also causes more serious pollution. Herein, a desalination-catalysis-irrigation integrated wood-based evaporator was presented by introducing cyano groups (-CN) in a metal-organic framework (MOF) system (M-NH-CN/wood). The ligand functionalization not only contributes to fine-tune the bandgap of MOFs to further enhance the light absorption, but also promotes peroxymonosulfate (PMS) activation to accelerate the degradation efficiency. Wood modified with MOFs can reduce system enthalpy of evaporation, resulting in a high evaporation rate of 2.24 kg m^-2 h^-1 for M-NH-CN/wood under 1 sun. This novel wood-based evaporator further contributes to the advancement of solar-driven interfacial evaporation and photocatalytic integrated systems, providing new perspectives for environmental remediation and sustainable development of agriculture.

基于配体功能化金属有机框架的蒸发器，用于同步淡水生产和农业废水修复

太阳能驱动的界面蒸发一直被认为是缓解水资源短缺的一种有前途的方法。但是，有机污染物在蒸发过程中通常会积聚在蒸发器上，这不仅降低了蒸发器的使用寿命，还会造成更严重的污染。本文通过在金属有机框架 （MOF） 系统 （M-NH-CN/wood） 中引入氰基 （-CN） 提出了一种海水淡化-催化-灌溉一体化木基蒸发器。配体功能化不仅有助于微调 MOF 的带隙以进一步增强光吸收，还有助于促进过氧一硫酸盐 （PMS） 活化以加速降解效率。用 MOF 改性的木材可以降低系统蒸发焓，导致 M-NH-CN/木材在 1 个阳光下的蒸发速率高达 2.24 kg m ^-2 h ^-1 。这种新型木质蒸发器进一步促进了太阳能驱动界面蒸发和光催化集成系统的发展，为环境修复和农业可持续发展提供了新的视角。
