Hydrocarbon reduction catalyst and vehicle exhaust gas purification device comprising the same

A vehicle exhaust gas purification device, which is provided on an exhaust pipe connected to an exhaust side of the engine to purify an exhaust gas of an engine, comprising:

• a housing disposed on the exhaust pipe and configured to receive the exhaust gas discharged from the engine, pass the received exhaust gas through the vehicle gas purification device, and discharge the passed exhaust gas rearward;
• a front-end catalyst built into the housing and configured to store hydrocarbons included in exhaust gas flowing into the housing through a front end of the housing;
• and
• a rear-end catalyst built into the housing and configured to purify exhaust gas passing through the front-end catalyst before it flows out to the rear end of the housing,
• wherein the front-end catalyst comprises:
• a first carrier comprising a cerium-zirconium composite oxide, and
• palladium supported on the first carrier, and
• the palladium is in an amount of about 1 wt % to about 10 wt % based on a total weight of the front-end catalyst.
