On the quantitative estimation of surface energetic heterogeneity of adsorbents and catalysts surfaces from TPD spectra based on the statistical rate theory of interfacial transport: variable heating rate as a promising way to establish the values...

An essential development is presented of our new method of quantitative estimation of the energetic heterogeneity of adsorbent and catalysts surfaces from Temperature Programmed Desorption spectra, based on the Statistical Rate Theory of Interfacial Transport. That method, presented in a series of our recent publications, involved a necessity of estimating, in other than TPD experiments, of certain adsorption parameters which are necessary to calculate the adsorption energy distribution. This was a serious inconvenience of that new method. In this paper, it is shown for the first time, that these parameters can be determined in the same TPD experiment by applying variable heating rate.
