摘　　要：ＣｕＯ／ＺｒＯ２合成甲醇催化剂的ＴＰＲ研究刘源胡泽善钟炳彭少逸（中国科学院山西煤炭化学研究所，太原０３０００１）关键词氧化铜，二氧化锆，程序升温还原，合成气，甲醇具有独特性质的ＺｒＯ２近年来在催化领域颇受关注［１，２］．Ｃｕ／ＺｒＯ２和Ｃｕ／ＺｎＯ／...ZrO 2 supported copper catalysts, in which the ZrO 2 was prepared by supercritical drying method, exhibited high activity and selectivity for methanol synthesis from CO/2H 2. TPR and XRD results showed that there were two kinds of copper oxide in the CuO/ZrO 2: one was bulk copper oxide and the other was well dispersed one. The latter one was the key active component; it could be reduced at lower temperature and its reduced product was well dispersed copper which was readily oxidized at room temperature in air.
