The removal of toluene by sepiolite supported with Fe₂O₃ by plasma catalysis was studied. Fe₂O₃/SEP catalysts were prepared by impregnation and characterized by Brunauer–Emmett–Teller, inductively coupled plasma, x-ray diffractometer, scanning electron microscopy, x-ray photoelectron spectroscopy, and H₂-TPR. Degradation efficiency of toluene under Fe₂O₃ loading, energy yield, carbon balance, CO₂ selectivity, and residual O₃ concentration were studied. The results show that sepiolite clay as a carrier can reduce the reduction temperature of Fe₂O₃. Fe₂O₃/SEP catalyst has good moisture resistance and catalytic capacity. 5Fe/SEP has the best catalytic effect due to its high lattice oxygen content and large specific surface area. After continuous discharge at constant energy density for 48 h, the catalytic ability of 5Fe/SEP does not decrease. The results indicated that sepiolite supported Fe₂O₃ catalyst is an efficient catalyst for toluene degradation by plasma-catalyst measure.

研究了等离子催化Fe ₂ O ₃负载海泡石对甲苯的去除。Fe ₂ O ₃ /SEP 催化剂通过浸渍制备，并通过Brunauer-Emmett-Teller、电感耦合等离子体、X 射线衍射仪、扫描电子显微镜、X 射线光电子能谱和H ₂ -TPR 进行表征。研究了Fe ₂ O ₃负载下甲苯的降解效率、能量产率、碳平衡、CO ₂选择性和残余O ₃浓度。结果表明，海泡石粘土作为载体可以降低Fe ₂ O ₃的还原温度。铁₂ O ₃ /SEP催化剂具有良好的防潮性和催化能力。5Fe/SEP由于其晶格氧含量高，比表面积大，催化效果最好。在恒定能量密度下连续放电48小时后，5Fe/SEP的催化能力没有下降。结果表明，海泡石负载的Fe ₂ O ₃催化剂是一种通过等离子体催化剂测量甲苯降解的有效催化剂。
