Abstract
A purifying catalyst includes catalyst powder composed of a transition metal oxide of which an average particle diameter is within 1 nm to 2 μm and in which an electron binding energy of oxygen is shifted to an energy side lower than 531.3 eV. The purifying catalyst shows good purification performance even when noble metal is not contained as an essential component.
