Abstract
The present invention relates to a catalyst for treating exhaust gas of natural gas vehicles, which can efficiently remove methane as a main ingredient contained in the exhaust gas. The catalyst for treating exhaust gas of natural gas vehicles has the excellent methane oxidation activity and also maintains the excellent catalytic activity even after the hydro thermal aging.
