제목 A study on the OSC characteristics of Rh-loaded ceria-zirconia mixed oxides prepared by continuous hydrothermal synthesis in supercritical water
초록 Ceria-zirconia mixed oxide is an important component as oxygen storage material for example in the three-way catalysts. Also rhodium plays an important role to improve the reduction property of ceria-zirconia mixed oxide because it can activate the reducing agent, i.e. H2. Continuous hydrothermal synthesis in supercritical water was used as a new synthesis method to obtain ceria-zirconia mixed oxides with better OSC properties. The OSC characteristics of Rh-loaded ceria-zirconia mixed oxides were investigated through physical characterizations with N2 adsorption, TPR, and O2-uptake.
