| 摘要: 利用程序升温还原(TPR)方法,研究了L型沸石基质中Ni2+、Eu3+离子的还原活性。同时,借助X光电子能谱(XPS)技术,对L型沸石基质中Ni2+、Eu3+离子还原前后的价态进行了分析,结果表明L型沸石基质中Ni2+、Eu3+离子的还原活性较高,可被氢气还原为低价甚至零价。镍离子的存在能促进Eu3+离子的还原,提高了Eu3+离子的 |

| Abstract: With the method of temperature programmed reduction(TPR), the reductive activity of the Ni2+ or/ and Eu3+ ions in zeolite Lwas studied.At the same time, the valances of Nickel and Europium after and before reduction were examined by means of X-ray photoelectron spectroscopy (XPS).It is shown that the reductive activity of the Ni2+ or/and Eu3+ ions in zeolite Lis very high.The existence of Ni2+ ion can promote the reduction of Eu3+ ion and raise the percentage of reduced Eu3+ ion. |
