Abstract
This chapter discusses the characterization of nickel (Ni) and platinum (Pt) zeolite catalysts by transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX), and n -hexane isomerization. The EDX analysis of the Ni and Pt bimetallic catalysts shows that the metal particles contain both metals, and from high-resolution transmission electron microscopy (HRTEM), it is observed that the bimetallic particles have crystallographic parameters of metallic nickel. The presence of small platinum amounts in the nickel catalysts produces more active catalysts for the n -hexane isomerization and also presents higher selectivity for the formation of dibranched hexane than the ones containing only platinum.
