几十年来,程序升温脱附法(TPD方法)被催化理论与实验工作者广泛地用于测定气体在固体催化剂表面的脱附活化能,和鉴定气体在固体催化剂表面的不同吸附态,某些热分解反应也采用了线性升温的方法。 我们知道,在TPD的实验处理上大多采用了忽略再吸附的近似。这里不妨在同一近似的基础上,在不影响原近似结果的条件下,采取进一步近似,以方便于覆盖度θ的计算。
For several decades, the temperature programmed desorption (TPD) method has been used extensively by catalytic theory and experimentalists to determine the desorption activation energy of gases on solid catalyst surfaces and to identify the different adsorption states of gases on solid catalyst surfaces. Some Thermal decomposition reaction also used a linear heating method. We know that the experimental treatment of TPD mostly adopts the approximation of ignoring reabsorption. Here may wish to be based on the same approximation, without affecting the original approximate results under the conditions to take further approximation to facilitate the calculation of coverage θ.
