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.

We report that the integration of filter membrane and Ca_(2)Nb_(3)O_(10)nanosheets(FM@CNO) UV photodetector(UV PD) shows high performance and excellent flexibility. The Ca_(2)Nb_(3)O_(10)nanosheets were prepared by a facile solid-state reaction and liquid exfoliation process. The Ca_(2)Nb_(3)O_(10)nanosheets can be integrated into the pores of a filter membrane via a simple vacuum filtration method. The FM@CNO UV PD shows high performance under 300 nm light illumination at 5 V bias, including high responsivity(0.08 AW^(-1)), high detectivity(1.1 × 10^(12)Jones), high UV/visible rejection ratio(3.86 × 10^(3)) and fast speed(0.12/1.24 ms). Furthermore, the FM@CNO device exhibits excellent flexibility after many bending *** addition, the FM@CNO array device was used as a pixel array detector for UV imaging. This work provides a novel approach to achieve high performance flexible PDs based on filter membrane and two dimensional materials.
