A NOstorage catalyst includes CHA zeolite, a transition metal ion-exchanged in the CHA zeolite, and a rare earth metal that is different the transition metal and is supported on the CHA zeolite. A method for preparing a NOstorage catalyst includes preparing a synthetic mother liquid including a zeolite raw material as a source of silica and alumina, a structure-inducing material, a complexing material, and a solvent, reacting the synthetic mother liquid to prepare a CHA zeolite, and supporting a transition metal and a rare earth metal that is different from the transition metal on the prepared CHA zeolite.

NOstorage catalyst and method for preparing the same

A catalyst for purifying exhaust gas includes a first catalyst including a first metal oxide on which platinum (Pt) and rhodium (Rh) are supported, and a second catalyst including a second metal oxide on which palladium (Pd) and platinum (Pt) are supported, wherein the first catalyst and the second catalyst are physically mixed.

Catalyst for exhaust gas purification and manufacturing method thereof

The present disclosure provides a catalyst for reducing CO and HC which is a core-shell particle including a core and a shell surrounding the core, the core includes metal oxide nanoparticles and noble metal nanoparticles fixed to the metal oxide nanoparticles, and the shell includes zirconia (ZrO), and a layer from which the metal oxide is removed between the core and the shell is included.

Catalyst for reducing carbon monoxide and hydrocarbon, and method for preparing the same

An exhaust gas post processing apparatus of a gasoline vehicle may include a housing mounted on the exhaust pipe to receive the exhaust gas discharged from the engine and to exhaust the exhaust gas passed through rearward thereof, a front end honeycomb catalyst unit embedded in the housing to primarily purify the exhaust gas introduced into the housing through a front end portion of the housing, and a rear end honeycomb catalyst unit embedded in the housing to secondarily purify the exhaust gas via the front end honeycomb catalyst unit before flowing out to a rear end portion of the housing, wherein the front end honeycomb catalyst unit includes a powder type catalyst in which an iridium-ruthenium alloy is supported on an aluminum oxide support powder, and the rear end honeycomb catalyst unit includes three-way catalyst powder which is configured to remove carbon monoxide, nitrogen oxides, and hydrocarbons simultaneously.
