Support and Temperature Effects in Platinum Clusters. 2. Electronic Properties

The effects of Brønsted acidity on the spatial structure and electronic properties of platinum clusters supported on zeolite Y have been examined with X-ray absorption (XANES and EXAFS) and X-ray photoelectron spectroscopy. The clusters contain 10−25 Pt atoms on average, with a nearest-neighbor dist...
