以表面分析技術研究異相催化反應機制，在過去數十年間解答了許多催化反應的問題，為化學工業帶來重大的革新。本文介紹中山大學化學系表面科學實驗室使用的兩種表面分析技術：程溫脫附技術 (TPD) 與反射吸收式紅外光譜 (RAIRS)。說明其原理及如何運用此技術解析分子在金屬表面上的反應制，獲取動力學資訊，並鑑定表面中間體與其吸附構型。

Mechanistic studies of heterogeneous catalysis using surface analytical techniques have solved many fundamental problems concerning active species and active sites on the catalysts. The surface science approach has brought many revolutionary ideas to the chemical industry. Here the working principles of two commonly adopted surface techniques, namely temperature programmed desorption (TPD) and reflection absorption infrared spectroscopy (RAIRS) are introduced, and the methods to extract the information about reaction kinetics, identities, and adsorption geometry of the surface intermediates are delineated.
