Abstract

In this paper, the advantages of employing a Derivative Temperature-Programmed Desorption (DTPD) curve in TPD analysis are demonstrated. Based on a series of theoretical DTPD curves obtained by computer simulation with double assumption of zero signal noise and no temperature gradients across the sample, a comparison is made between the TPD and DTPD curves, and it is found that the approach can (a) estimate desorption order, (b) raise resolving power, and (c) eliminate baseline drift. The equations for calculating kinetic parameters from DTPD curves are also presented. The results show that these equations are valid.
