Abstract

Front cover image: In article number 10.1002/cnl2.79, Shilin Chen and her co-workers focus on a low-cost method to fabricate an advanced solar evaporator. Lignosulfonate was used as raw material by carbonization to construct lignosulfonate-derived biochar powder. Porous biochar powder as solar absorber was cross-linked with polyvinyl alcohol to prepare a solar interfacial evaporator with efficient desalination performance. The porous structure is advantageous for light capture and multiple scattering, achieving excellent solar energy absorption. Due to the weakened hydrogen bonds between water molecules and polymer network chains, the water molecules are activated to form intermediate water and are evaporated with minimized energy by their configuration. This work provides an economic and efficient strategy for solar-driven desalination and a possible way for high-value utilization of lignin.

封面图片：在文章编号10.1002/cnl2.79中，Shilin Chen和她的同事专注于一种低成本的方法来制造先进的太阳能蒸发器。以木质素磺酸盐为原料，通过炭化法制备木质素磺酸盐衍生的生物炭粉。将多孔生物炭粉末作为太阳能吸收剂与聚乙烯醇交联，制备了具有高效脱盐性能的太阳能界面蒸发器。多孔结构有利于光捕获和多次散射，实现了优异的太阳能吸收。由于水分子和聚合物网络链之间的氢键减弱，水分子被活化形成中间水，并通过其构型以最小的能量蒸发。这项工作为太阳能海水淡化提供了一种经济有效的策略，并为木质素的高价值利用提供了一条可能的途径。
