| 摘 要： | TPD技术1]已成为研究固体表面性质的重要手段,本文在总结前人工作的基础上考察了TPD谱峰峰宽和相应参数与脱附活化能(Ed)之间的变化规律,证明用任意峰宽法或半峰宽法测定Ed值有很好的实用性,该法直接运用TPD谱图参数,无需另外作图,故十分快速、简便,与其它方法比较,结果吻合。

| Abstract: | Three equations to calculate activation energy of desorption (Ed) were obtained from Polan-gi-Wagner model and TPD profile,Ed values can be calculated quickly from TPD peak width AT and its corresponding parameters by using the three equations. Comparating with other methods, the results are consistent with each other. |
