(57) [Problem] To provide an exhaust gas purifying material and an exhaust gas purifying apparatus capable of efficiently burning particulates by increasing the reaction efficiency and trapping efficiency between exhaust gas and a catalyst. SOLUTION: A gas inlet side or a gas outlet side of each adjacent ventilation cell of a wall-through type filter 2 composed of an aggregate of ventilation cells separated by gas permeable partition walls is alternately plugged, and is mainly used. The molar ratio of a copper element (a) having a crystal structure of CuV 2 O 6 to a vanadium element (b) (a: b) Exhaust gas having a molar ratio (c: d) of a copper vanadium compound (c) of 1: 1.5 to 1: 3.5 to cesium sulfate (d) of 1: 3 to 1: 3.5. The exhaust gas purifying material 1 is formed by coating the purifying catalyst 4 on the inner wall surface of the ventilation cell. |
