Rare Metals 2024年第9期43卷 4344-4355页

作者： Zhuo-Fan Yu Ye Yang Hai-Feng Zhuang sheng-Dao Shan Mihail-Simion Beldean-Galea Qing-Quan Xue xiao-Feng shen Shi-Jie li Key Laboratory of Recycling and Eco-Treatment of Waste Biomass of Zhejiang Province School of Environmental and Natural Resources Zhejiang University of Science and Technology Faculty of Environmental Science and Engineering Babes-Bolyai University Key Laboratory of Pollution Exposure and Health Intervention of Zhejiang Province Interdisciplinary Research Academy (IRA) Zhejiang Shuren University National Engineering Research Center for Marine Aquaculture Institute of Innovation & Application Zhejiang Ocean University

The application of metalDorganic frameworks(MOFs) is hindered by several crucial factors, including low photocatalytic efficiency, poor stability and challenges in recycling. In this study, MIL-53(Fe) was grown in situ on a charcoal sponge(CS) with a large surface area,excellent mechanical properties, and high photocatalytic efficiency using a solvothermal method, thus addressing the above-mentioned shortcomings of MOF ***, CS/MIL-53(Fe) has an amazing light-harvesting capacity in the visible range, leading to a significant improvement in the utilization of light. The results of the experiments indicate that CS/MIL-53(Fe) displays a higher photocatalytic activity(87% Cr(VI)) when exposed to visible light than CS(58%) or MIL-53(Fe)(27%),attributing to the increased separation of photogenerated carriers. e-is the main reactive radical and dominates the photocatalytic reduction process, rooting from that e-can reduce Cr(VI) to low-toxicity Cr(III). This study presents a novel method for constructing photocatalysts with large surface areas, superior mechanical characteristics, and enhanced photocatalytic performance. Additionally, it achieves the resource utilization of agricultural and forestry waste.
