Abstract:In this project, we have shown that the hydrothermal method can be used to tune
the shape/size of CeO2 nanocrystals. CeO2 nanorods and nanocubes have been successfully
prepared at low and high hydrothermal reaction temperature, respectively. The chemisorption
analysis and CO oxidation test evidenced that a high oxygen vacancy concentration in CeO2
nanorods leads to a lower temperature reducibility and superior catalytic activity, compared to
CeO2 nanocubes. Out of this project, three refereed and two proceeding papers were published,
along with several oral presentations made by PI and students
