Abstract

The present invention provides a catalyst having titanium oxide and other catalytic active composition to resolve and remove toxic materials in the exhausted gases, it is characterized in that the ratio (B/L) of Bronsted acid (B) and Lewis acid (L) is in the range of 0/1~10/1. The present invention also provides a method for using said catalyst to treat exhausted gases.
