Abstract
EXAFS measurements by means of synchrotron radiation of CuZnO Al 2O 3 CO shift catalysts and various reference compounds (Cu, CuO, Cu 2O, ZnO, and spinels) show the presence of CuO and ZnO in fresh catalysts and of highly dispersed Cu and ZnO after activation and reduction. The presence of Cu 2O and spinels is excluded within the detection limits. The results are in agreement with previously reported XANES studies of the same catalyst samples.
