摘要
常用的觸媒表面酸性中心種類，強度，數量及性質的測定方法有四種：（一）滴定及指示劑法用於觸媒酸性強度及含量的初步篩選工作。（二）熱分析及氣體鹼吸附的實驗溫度與觸媒反應溫度相近。（三）光譜法是最有力的酸性中心鑑定方法。（四）模式反應速率的測定提供了固體酸性觸媒在催化作用上最有用的資料。

The measurements of surface acidity on solid catalysts give the information about the nature, number, strength and environment of acid sites. The results of amine titration and adsorption of indicator provide the primary information about the strength and amount of acid sites. The thermal analyses on gaseous bases adsorbed catalysts are at or near the temperatures at which catalyzed reactions occur. The most powerful tool for the characterization of acidic groups on solid surfaces is spectroscopy. To catalytic chemist, the most relevant approach for the determination of surface acidity is the rate measurements of a simple acid-catalyzed reaction.
