Parameter determination of a thermal desorption model
Autor: Dobrivoje Popovic, G. Schulz-Ekloff, S. Zhou
Publikováno v: Journal of Thermal Analysis. 41:767-788
A new method for the analysis of thermal desorption spectra is presented, based on the experimental peak maximum functions for temperatureT m(β) and pressureP m(β) and a rigorous mathematical treatment. The resonant heating rate βr is determined,

Structure, Photoabsorption and Reversible Reactivity of Faujasite-Supported Dispersions of CdO and SnO2
Autor: G. Schulz-Ekloff, H. J. Schwenn, Michael Wark, Nils I. Jaeger
Publikováno v: Berichte der Bunsengesellschaft für physikalische Chemie. 96:1727-1731
High dispersions of CdO and SnO2 in a faujasite matrix are obtained by consecutive ion exchange, alkaline precipitation and calcination. The particle sizes in the range 5 to 20 nm are inferred from electronic spectra, transmission electron microscopy

FTIR study of the reduction of faujasite NaX exchanged with chloropentammine iridium(III)
Autor: G. Schulz-Ekloff, H. Bischoff, Nils I. Jaeger
Publikováno v: Catalysis Today. 8:501-508
The chemisorption of CO has been used to characterize the state of reduction of Ir(III)-chloropentammine exchanged NaX. The degree of reduction and the dispersion of the Ir metal strongly depends on the reduction conditions.
