• 中文摘要： 擔體承載之氧化鑭鈷觸媒是經由二個步驟製備而成,在第一個步驟中氧化鋁先與二價之鎂離子作用以使其表面改質,在第二個步驟中則利用此改質之氧化鋁來承載氧化鑭鈷。製備時之一些變數如鎂及氧化鑭鈷之含量以及在每一步驟中之煆燒溫度都將在本文中探討,所製備之觸媒將以表面積之測量、ESCA及甲苯之氧化來鑑定其相關性質。
• 英文摘要： Supported LaCoO/sub 3/ catalysts were prepared by a two-step process. In the first step, .gamma.-alumina reacted with Mg/sup 2+/ to result in a modified surface on it. Then the modified alumina was used to support LaCoO/sub 3/. Effects of the preparation variables such as Mg and LaCoO/sub 3/ loadings as well as the calcination temperatures in each step were studied. These catalysts were characterized by BET surface area measurement, ESCA analysis and toluene oxidation.
