摘要
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 materials.Notably,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.
