The different adsorbed species such as sulfates sulfites and adsorbed sulfur dioxides under various temperature, pressure and evacuated treatment conditions were characterized by in situ-IR. In the absent of oxygen, two bands were observed at 1050cm〓 and 1330cm〓, the former is the weakly chemisorbed sulfur dioxide species and the latter is the strongly chemisorbed SO〓.

首次利用正电子淹没技术求取了CeO〓在MgAl〓O〓上单层分布的阈值为0.075g／gMgAl〓O〓，此值略小于利用XRD法求取的单层分布阈值0.08g／gMgAl〓O〓，并且发现催化剂的氧化吸硫活性，O-Ps的生成率与CeO〓的负载量之间良好的对应关系，当CeO〓在MgAl〓O〓上形成单层分布时，O-Ps的生成率最小，此时，催化剂的活性最优。
