Abstract
Provided is a palladium catalyst in which palladium (Pd) is used as a catalyst active component, and particularly a novel palladium catalyst which can purify CO and THC with high efficiency even under a fuel-rich atmosphere having a high space velocity (SV). Proposed is a palladium catalyst having a substrate and a catalyst layer that contains palladium acting as a catalyst active component, an inorganic porous material acting as a catalyst support and ceria (CeO) particles acting as a promoter component, in which a mass ratio (Pd/CeO) of a content of the palladium in the catalyst layer to a content of the ceria particles in the catalyst layer is 0.0014 to 0.6000.
