| 摘 要： | 通过化学还原法制备了胶体镍催化剂，并将其用于丙烯腈加氢反应。通过X射线衍射和透射电镜对催化剂进行了表征，考察了制备条件对催化性能的影响。结果表明，当c(Ni2+)＝10 mmol·L-1 、温度90 ℃和n(N2H5 OH)∶nNi2+)=8时，制得的胶体镍具有较好的稳定性和催化活性，胶体镍的平均粒径为30 nm。

| Abstract: | Colloidal nickel acrylonitrile hydrogenation catalyst was prepared by chemical reduction. XRD and TEM were used for characterization of the catalyst. The colloidal nickel with average particle diameter of about 30 nm, exhibited higher hydrogenation activity and good stability, with optimum preparation condition as follows: 90 ℃, c(Ni2+)10 mmol·L-1,c(hydrazine)=80 mmol·L-1 |
