摘要：
LaFeO3 and Fe(OH)(3)-modified LaFeO3 were used as supports for the nano-gold catalysts, respectively. The catalysts were prepared by a deposition- precipitation method and were characterized by XRD, XPS, AAS and BET. Furthermore, the activity and stability, involving the reaction and storage process, were investigated. The results demonstrate that the addition of Fe(OH)(3) could improve the stability both in the continual reaction and the preserving process. Therefore the strong interaction between the gold species and Fe(OH)(3) could inhibit the aggregation of gold particles and increase the stability of the catalyst.
