| 摘 要： | 用XRD，FT－IR，XPD和Mossbauer对样品进行表征。Ni的加入有2／3以氢氧化物型态存在，增加了催化剂表面ON∧－的浓度，使催化剂在较低汽气比条件下具有较高催化活性，Ni不可能进入Fe3O4尖晶石晶格的A位，从而改变催化剂的电子结构和几何结构，起结构助剂作用。

| Abstract: | Catalysts were characterized by XRD,FT-IR,XPS and Mssbauer.The addition of Ni,2/3 of which exit with hydroxide which raises denity OH - on the surface of the catalyst improved the catalytic activity under the low vap./gas ratio condition.Ni may enter A space of Fe 3O 4 spine lattice.It is guide to change electronic and geometric structure and to act the effect of framework auxiliary. |

| Keywords: | Ni high-temperature-shifting of catalyst low vap /gas |
