Development of Three-way Catalyst Using Composite Alumina-Ceria-Zirconia

Takaaki Kanazawa; Juji Suzuki; Toshihiro Takada; Tadashi Suzuki; Akira Morikawa; Akihiko Suda; Hideo Sobukawa; Masahiro Sugiura

Abstract To realize the high performance of the three-way catalyst, a new catalytic promoter. “ACZ” was proposed. ACZ consists of nanometer-size CeO2-ZrO2 solid solution (CZ) particles and diffusion barrier layers made of alumina (A) among the CZ particles. The specific surface area of ACZ was larger than that of the conventional CZ after durability test. The sintering of Pt on the ACZ-added catalyst is inhibited and the crystal size of CZ in the ACZ-added catalyst is smaller than that in the CZ-added catalyst. The dynamic OSC and the light off temperature of the ACZ-added catalyst are improved.
