Bam@MIL-125/Ag evaporator: Synergistically boosting evaporation and photodegradation for Holistic water management

Xinyu Cai,Yiduo Chen,Dandan Wang,Zhongming Su,Weiting Yang

Here, a biomass-based composite interfacial evaporation system utilizing a Ti-MIL-125-NH 2 /Ag (Ti-MIL-125/Ag; MIL-125/Ag) catalyst was successfully developed, which innovatively achieved synergistic enhancement of photothermal conversion and photocatalytic degradation. Initially, the precisely engineered Ag nanoparticles-modified Ti-MIL-125-NH 2 significantly enhanced visible-light absorption capacity and charge carrier separation efficiency. Furthermore, a Bam@MIL-125/Ag three-dimensional porous interfacial evaporator was constructed using eco-friendly and low-cost bamboo substrate through the sodium alginate gelation. At a height of 1.5 cm, 5 wt% of Ag loading, and a content of 20 mg of Ti-MIL-125/Ag in the Bam@MIL-125 evaporator, the Bam@MIL-125/Ag system under 1 kW·m −2 simulated sunlight demonstrated an evaporation rate of 1.45 kg·m −2 ·h −1 and a solar-to-vapor conversion efficiency of 81.2 %. Notably, leveraging photo-generated free radicals from Ti-MIL-125/Ag, the Bam@MIL-125/Ag evaporator achieved efficient removal (98.67 %) of volatile organic compounds (VOCs) in water through the photocatalytic degradation process. Furthermore, when operating continuously for 56 h in a 3.5 wt% NaCl solution, the Bam@MIL-125/Ag evaporator maintained an evaporation rate above 1.4 kg·m −2 ·h −1 , demonstrating excellent stability, salt resistance, and heavy metal removal capabilities in practical applications. This work provides an innovative strategy for designing MOF-based evaporators that combine high-performance water production with advanced purification functionality.
