本文考察了铜含量对CuZrO2和Cu-La2O3ZrO2催化剂性能影响。结果表明,当铜含量较低时,铜在催化剂中以高分散状态存在,并随铜含量增加,催化剂活性线性增加。当铜含量超过某一值,部分铜组分以体相铜形式存在,催化剂活性随铜含量变化不明显。因此,高分散铜为影响CuZrO2催化剂活性主要因素。 This article examines the copper content of CuZrO2 and Cu-La2O3ZrO2 catalyst performance. The results show that when the content of copper is low, copper exists in the highly dispersed state in the catalyst. With the increase of copper content, the activity of the catalyst increases linearly. When the copper content exceeds a certain value, part of the copper component is in the form of bulk copper, and the activity of the catalyst does not change obviously with the copper content. Therefore, highly dispersed copper is the main factor affecting CuZrO2 catalyst activity.
