程序升温脱附(TPD)技术在固体表面化学和催化等研究领域中已得到广泛的应用.但由于缺乏有力的理论处理手段,对TPD谱图所提供的信息利用率不高,甚至仍在运用某些错误的处理方法.为此,作者曾对一级脱附反应TPD谱图作过理论分析.本文进一步对二级脱附反应(均匀表面、无再吸附过程)TPD谱图作理论分析. Programmed temperature-programmed desorption (TPD) has been widely used in the field of solid surface chemistry and catalysis, etc. However, due to the lack of powerful theoretical methods, the utilization of information provided by TPD spectroscopy is not high or even used Some erroneous processing methods.Therefore, the author has made a theoretical analysis of the first-order desorption reaction TPD spectra.This paper further theoretical analysis of TPD spectra of secondary desorption reaction (uniform surface, no reabsorption process).
