采用硫酸亚铁和均苯三甲酸为原料,在室温条件下以水为溶剂,快速合成高结晶度和高稳定性的MIL-100(Fe)纳米颗粒。利用XRD、SEM、FT-IR和UV-Vis DRS对所合成的MIL-100(Fe)纳米颗粒进行表征。以H2O2为助催化剂,在紫外光(或可见光)照射下,MIL-100(Fe)纳米颗粒可将RhB高效光催化降解。循环光催化实验表明,MIL-100(Fe)的光催化性能和晶体结构极其稳定,在废水净化领域具有良好的应用前景。
Highly crystalline and stable MIL-100(Fe) nanoparticles were synthesized from aqueous phase at room temperature via the utility of FeSO4 and deprotonated trimesic acid.The obtained nanoparticles were characterized by XRD,SEM,FT-IR and UV-Vis DRS.MIL-100(Fe) nanoparticles exhibited excellent photocatalytic performance for organic dye,Rhodamine B,in the presence of H2O2 as a co-catalyst under UV (or visible)light irradiation.The stability and recyclability of nanoparticles were further confirmed by multiple runs photo-degradation of RhB,suggested the potential applications of MIL-100(Fe) in waste water treatment.
