• 中文摘要： 茲以臨溼浸漬法製備鉬含量在0.47-8.13wt%之MoO/sub 3//SiO/sub 2/觸媒。製備時以不同酸鹼之溶液為之,酸鹼度對氧化鉬表面結構之影響則由X-射線繞射光譜(XRD),紫外線光譜(UV),以及程溫還原之結果來鑑定,反應性方面則由異丙醇之部分氧化測試。有三種氧化鉬之結構被發現,鉬的含量及溶液酸鹼度都會影響此三種結構之各別量,各結構之觸媒性質也不一樣。
• 英文摘要： MoO/sub 3//SiO/sub 2/ catalysts of 0.47-8.13 wt% Mo were prepared by dry impregnation. In the preparation of the catalysts, various solution acidities were used. The acidity effects on molybdena surface structures were studied by XRD, UV, and TPR. Partial oxidation of isopropanol was adopted as the test reaction for the catalysts. Three different molybdena species were detected. Both molybdena loading and the solution acidity affected the amount of each species. Unique catalytic property was found for each species.
