一、引言程序升温脱附简称 TPD(Temperature programmedDesorption),是Amenomiga和Cvetanvic于1963年首先提出的一种测试技术,近十多年来发展迅速,已成为研究催化剂表面性质,吸附中心强弱,数目及表面反应的有效手段。由于它所需设备较简单和数据处理较方便,我们已将它作为中级物理化学实验测定某些动力 I. INTRODUCTION Temperature programmed desorption (TPD) is a test technique first proposed by Amenomiga and Cvetanvic in 1963. It has developed rapidly over the past decade and has become one of the most important research topics in the field of catalyst surface properties, the strength of adsorption centers, the number of And surface reaction of effective means. Because of the simpler equipment it requires and the ease of data processing, we have determined it as a mid-level physico-chemical test
