中文摘要:
      利用XRD、TPR及固定床微反技术,研究了添加FeOx对ZrO2载体结构稳定性和催化性能的影响。结果表明,FeOx对载体ZrO2具有良好的热稳定性,能阻止ZrO2从四方晶型向单斜晶型的转变;FeOx与载体ZrO2之间的相互作用,能促进FeOx在载体表面的分散,并提提高FeOx/ZrO2催化剂的氧化和还原性能。
英文摘要:
      The effect of introducing FeO\- x to ZrO 2 support on the structural stability and the oxidation activities of CO was studied using XRD, TPR and fixed bed microraction techniques. It was found that introduction of FeO\- x improves the thermal stability of ZrO 2 and inhibits the phase transformation of tetragonal ZrO 2 to monoclinic ZrO 2. The interaction between FeO\- x and ZrO 2 has effect on the dispersion of FeO\- x on the support surface, which increases the oxidation activities of Fe\-2O\-3/ZrO 2 catalysts.
