Process of preparing catalyst supporting highly dispersed platinum particles.

摘要

Disclosed herein is a process of preparing a catalyst having narrow particle size distribution and supported with monodispersed platinum particles of which a particle size is about less than 20 ANGSTROM . In the present invention, allyl alcohol and hydrazine hydrate are employed in place of a sulfur-containing agent for supporting the platinum particles on a support thereby avoiding the contamination of the sulfur component and the high temperature treatment for decomposing the sulfur-containing agent. Accordingly, the resulting catalyst contains no sulfur contaminant and substantially no agglomerated platinum particles.
