ABSTRACT:
The present invention provides an exhaust gas treatment catalyst characterized by containing a compound oxide expressed by the following general formula (1),in-line-formulae description="In-line Formulae" end="lead"?AMxOy   (1)in-line-formulae description="In-line Formulae" end="tail"?(wherein A represents an alkali metal or alkaline earth metal, M represents Cr, Mn, Fe, Co or Ni, O represents oxygen, and 0<x≦4 and 0<y≦8)and an exhaust gas treatment method using the said catalyst. According to the present invention, there can be provided an exhaust gas treatment compound oxide that can effectively remove particulates and NOx contained in exhaust gas with a high oxygen concentration that is discharged from a diesel engine etc., and also has excellent resistance to sulfur poisoning.
