中文摘要:
      采用XRD、TEM、TPR及XPS等表征手段,对共沉淀法制备的Au/NiO催化剂的活性中心,载体的结构及状态进行了研究。结果表明,活性中心金以纳米尺寸高度分散于载体表面,部分金可能呈现氧化状态,载体结晶适度。
英文摘要:
      XRD, TEM, TPR and XPS characterization means were used to study the structure and state of active center and support in Au/NiO catalysts prepared by coprecipitation. The results show that the size of gold particles highly dispersed on the surface of support is in the range of several nanometers, and it is possible that a certain fraction of gold particles has a positive oxidation state, while the support possesses a proper crystallinity.
