摘要

采用微波烧结法快速合成了双钙钛矿Sr2FeMoO6。用XRD分析了样品的晶体结构。结果表明,合成的样品为Sr2FeMoO6,具有四方晶体结构和I4/mmm空间基团。电输运性能测试表明,样品在80~300 K的温度范围内表现出典型的半导体行为。研究了样品用量、光照射源和时间对降解效率的影响。结果表明,Sr2FeMoO6对染料酸性红B具有良好的降解活性,在适当的条件下脱色率接近100%。同时,提出了一种与降解过程相关的机理。

Research on Degradation of Dye Acid Red B by Sr2FeMoO6 Synthesized by Microwave Sintering Method
Double perovskite Sr2FeMoO6 was synthesized rapidly by microwave sintering method. The crystal structure of the sample was investigated by XRD. It shows that the as-synthesized sample is Sr2FeMoO6 with tetragonal crystal structure and I4/mmm space group. The test of electrical transport properties shows that the sample exhibits typical semiconductor behavior in the temperature range of 80~300 K. The influence of the dosage of the sample, light irradiation sources, and time on the efficiency of degradation have been studied. The results show Sr2FeMoO6 exhibits excellent degradation activity for dye Acid Red B, the decolorization rate is close to 100% under proper conditions. Meanwhile, a mechanism related to the process of degradation is proposed.
