An increase in surface area is effective way to enhance photocatalytic activity, then it is important to synthesize nanoparticles. In this study, we attempted to synthesize CeO₂ nanoparticles by crystallized glass method. It was found that crystallization temperature plays an important factor to control the morphology and size of CeO₂ nanoparticles. Relationship between photocatalytic acetaldehyde degradation and crystallization temperature is discussed.
