PROBLEM TO BE SOLVED: To treat NOx or organic halides stably over long time even at low temperature range, and especially to treat NOx or organic halides included in exhaust gas stably over long time even when sulfur oxides are included in exhaust gas.SOLUTION: A catalyst for treating an exhaust gas including NOx or organic halides contains a ternary system complex oxide or a mixed oxide of titanium, molybdenum or silicon as a catalyst A component, a compound of at least one element of vanadium, niobium or tantalum as a catalyst B component, and a compound of at least one element of manganese, iron, cobalt or zinc as a catalyst C component, and has the molybdenum content in the catalyst A component of 10 to 30 mass% as oxide. |
