Abstract
The structure of rhodium in an ultradispersed 0.57 wt % Rh/y-Al,O, catalyst before and after CO adsorption was
studied with extended X-ray absorption fine structure (EXAFS), X-ray photoelectron spectroscopy (XPS), electron spin resonance
(ESR), temperature programmed reduction (TPR), CO infrared spectroscopy, and H2 and CO chemisorption. With the aid
of these complementary techniques,
