HYDROGEN-GENERATING CATALYST, AND EXHAUST GAS PURIFICATION CATALYST

摘要

This hydrogen-generating catalyst comprises: a noble metal; an oxide which supports the noble metal, and which includes lanthanum (La) and zirconium (Zr); and an oxygen occlusion/release material. This exhaust gas purification catalyst includes: a first catalyst unit comprising a noble metal, and an oxide which supports the noble metal, and which includes lanthanum (La) and zirconium (Zr); a second catalyst unit comprising the oxygen occlusion/release material; and a holding material which holds the first catalyst unit and the second catalyst unit in a state of being separated from each other.
