Abstract
Platinum has been supported on NaY zeolite by ion exchange of Pt(NH3)4 2+. Clustering of Pt atoms into a 1 nm cluster, and three-dimensional quantum-size wire (3 nm thick) network (greater than 100 nm) from redu ction of the Pt species has been investigated by extended X-ray absorp tion fine structure transmission electron microscopy and xenon adsorpt ion measurements.
