Catalytic behavior and surface chemistry of copper/alumina catalysts for isopropanol decomposition
TLDR
In this paper, a linear relationship was found between the kinetic constant and the surface area of copper metal, and it was therefore proposed that surface Cu(0) species are responsible for the dehydrogenation.About:

Characterization of CuAl2O3 catalysts
TL;DR: In this article, the interaction of cupric ions with γ-alumina supports was studied by physical characterization of a wide range of catalyst preparations, and the results from different techniques, including extended X-ray absorption fine structure (EXAFS), Xray absorption edge shifts, Xray diffraction, ESR, ESCA, and optical spectroscopy, were combined with prior work to develop a coherent description of the phases present and cation site distribution in the virgin and aged catalysts.
