Preparation and Catalytic Property of CeO₂ Nanoparticles/YTZ Pellet Catalyst

Abstract

This study deals with the preparation of CeO₂ nanoparticles (NPs) catalyst supported by YTZ ball ceramics, and investigations of its morphology and hydrogen oxidation property. A CeO₂ NP layer was prepared by a simple dipping process. As the results, the CeO₂ NPs maintained the high dispersion state even after heat treatment at 1000°C. According to H₂-TPR measurement, it was also found that a CeO₂ NPs-modified YTZ sample has better catalytic property than CeO₂ powder. Thus, the catalytic functionalized YTZ ball-type ceramic was provided by simple processing with the modification of CeO₂ NPs as a novel catalytic material.
