LaFeO3钙钛矿催化湿式氧化苯酚的研究

Study on wet air oxidation of phenol catalyzed by LaFeO3 perovskite

    摘要
  • 摘要: 本研究采用固相球磨法制备了四种不同球磨时间的LaFeO3钙钛矿催化材料，并将其用于催化湿式氧化苯酚反应，探讨了球磨时间对LaFeO3钙钛矿催化剂催化湿式氧化苯酚水溶液性能的影响。采用XRD、H2-TPR、TG-DTA、FT-IR、N2物理吸附、XPS等手段对LaFeO3钙钛矿催化材料进行了表征。结果表明，在反应温度为200 ℃、空气压力5 MPa、苯酚初始浓度4000 mg/L时，经过240 min的催化氧化反应后LaFeO3-6催化材料最终的COD去除率为94.5%。

     

    Abstract: In this paper, four kinds of LaFeO3 perovskite catalytic materials with different ball milling time were prepared by solid phase milling method and used to catalyze the wet air oxidation of phenol. The effect of milling time on the performance of LaFeO3 perovskite catalyst for wet air oxidation of phenol aqueous solution was investigated. LaFeO3 perovskite catalytic materials were characterized by XRD, H2-TPR, TG-DTA, FT-IR, N2 physical adsorption and XPS. The results show that when the reaction temperature is 200 ℃, the air pressure is 5 MPa and the initial concentration of phenol is 4000 mg/L, the final COD removal rate of LaFeO3-6 catalytic material is 94.5% after catalytic oxidation of 240 min.
