| 摘 要： | 采用沉积沉淀方法制备了一系列Au—NiO／TiO2催化剂，考察了助剂NiO的加入量、焙烧温度对催化活性的影响。研究表明：助剂NiO的加入可以明显提高Au—NiO／TiO2催化甲醇水蒸汽重整制氢的活性；Au与NiO的配比存在最佳值，当Au负载量（质量分数）为2％，Au与NiO的质量比为1：5时，催化效果最佳；2％Au-10％NiO／TiO2催化剂的催化活性随焙烧温度的升高而降低。

| Abstract: | A series of Au/TiO2 catalysts were prepared by the deposition - precipitation method. The influences of NiO loading and calcination temperature on the catalytic activity of Au/TiO2 catalysts for the hydrogen production from methanol steam reforming were studied. The results show that NiO promoter can enhance the catalytic activity of methanol steam reforming; Au-NiO/ TiO2 with 2% Au loading, in which Au/NiO weight ratio is 1 ： 5 exhibits the optimal catalytic performances; the activity of the 2% Au-10%NiO/TiO2 catalyst decreases with the increase of the calcination temperature. |
