Cerium-doped barium zirconate (Ce-doped BaZrO3) fine particles with high crystallinity was prepared by a hydrothermal reaction using barium hydroxide, CeCl3, and a Zr-triethanolamine complex. Characterization of the Ce-doped BaZrO3 particles revealed that utilization of the water-stable Zr-triethanolamine complex was an efficient way to introduce cerium ions into the BaZrO3 perovskite crystal structure. The three-way catalytic activity of the Ce-doped BaZrO3 for an exhaust gas conversion reaction was investigated under a stoichiometric condition (CO 0.5%, C3H6 400 ppm, NO 500 ppm, O2 0.49%, H2 0.17%, CO2 14%, H2O 10% in N2). The Ce-doped BaZrO3 exhibited a remarkable low temperature NOx cleaning performance when the Ce-doped BaZrO3 was applied as an alternative for an Al2O3 support.
