摘要：

Nia(0.1)Mg(0.9)O nanocrystalline powders were prepared by surfactant assisted precipitation method and employed as catalyst in dry reforming. The powders were characterized by using XRD, BET, SEM, TGA/DSC and TPR techniques. The results showed that the surfactant to metal mole ratio affects the textural properties. Increasing in surfactant to metal mole ratio increased the specific surface area and decreased the crystallite and particle size. The Ni0.1Mg0.9O with the highest surface area (115.39 m(2) g(-1)) was employed as catalyst in dry reforming. This catalyst showed a high catalytic activity and stability during 122 h time on stream without any decrease in methane conversion.
