| Abstract: | Platinum has been supported on NaY zeolite by ion exchange of Pt(NH3)42+. Clustering of Pt atoms into a 1 nm cluster, and three-dimensional quantum-size wire (3 nm thick) network (greater than 100 nm) from reduction of the Pt species has been investigated by extended X-ray absorption fine structure transmission electron microscopy and xenon adsorption measurements. |
| Keywords: | Pt cluster supported on zeolites quantum-size Pt wire network metal-support interaction EXAFS TEM |
