To achieve sustainable desalination and water purification,solar interface evaporation technology is an effective means due to its high energy *** photothermal conversion materials and surface design are crucial for the interfacial solar evaporation *** to design water transport routes and thermal insulating layers simultaneously is one of the major challenges to solar interface evaporation technology ***,this work reports an arch-shaped wood evaporator(pine@carbon black(CB)-metal-organic framework-801(MOF-801)-36%)for efficient,fast and continuous interfacial solar evaporation,which is composed of an arch-shaped wood substrate,MOF-801,and CB as a light absorption *** archshaped structure has a double-sided evaporation effect,which has a synergistic effect on augmenting solar evaporation *** addition,the in-situ growth of MOF-801 in pretreated wood microchannels renders the wood evaporator a significant function of reducing the equivalent enthalpy of evaporation due to the reduction of the hydrogen bonding density of water molecules as they pass through the wood *** best evaporation rate of the arch-shaped wood evaporator can reach 2.535 kg·m^(−2)·h−1,and the efficiency reaches 93.7%under the irradiation of 1 sun ***,it could be used for desalination and wastewater treatment to collect fresh water that meets drinking requirements set by the World Health Organization(WHO).This integrated evaporator provides an efficient way for commercial portable photothermal conversion and new ideas for advanced solar-driven water treatment technology.

Interfacial solar evaporation technology is considered one of the most promising strategies for alleviating the scarcity of freshwater resources. However, solar-driven evaporation technology cannot eliminate the pollutants in the residual *** solve this problem, we have prepared a two-in-one solar-driven evaporation/photocatalysis system by decorating MoS2/covalent organic framework (COF) heterojunctions on wood (MoS2/COF-wood). Thanks to the unique porous structure of wood, it provides a strong guarantee for water transport and vapor release during the evaporation process. The introduction of MoS2and COFs can promote the breaking of hydrogen bonds between water molecules, which leads to a significant decrease in the enthalpy of evaporation, achieving a water evaporation rate as high as 2.17 kg m-2h-1under 1 sun irradiation. Meanwhile,the resulting MoS2/COF-wood exhibits good salt resistance and reusability. In addition, the heterojunctions formed between COFs and MoS2can effectively inhibit charge carrier complexation and improve the photocatalytic degradation ability of pollutants (over 99%). This study highlights the construction strategy of bifunctional wood-based materials for freshwater production and wastewater remediation.

21世纪以来,梦已然成为阎连科小说叙述的重要内容。从《丁庄梦》到《日熄》,阎连科或是在小说中插入大量的梦境描写,或是直接将小说架构为一场“梦幻”。在《丁庄梦》等作品中,梦境还只是个体欲望的隐性表达;到了《日熄》,阎连科借助对集体梦游的刻画,表现出整个人类的集体无意识,尤其是阴影原型所象征的人性恶。梦境书写因此成为阎连科探寻人性的有效方式。除此之外,梦境书写的叙述策略也表现出阎连科的创作无意识:对自我生命惶惑的表达和对写作困境的体认。
