The invention discloses a catalyst with meso pore characteristics and an application thereof. The catalyst with meso pore characteristics is produced by loading ingredients with catalytic activity onto the inner tunnel surface of a meso pore molecular sieve carrier, wherein the meso pore molecular sieve carrier contains one or more elements selected from the group consisting of MCM-41, MCM-48, SBA-15, SBA-16, KIT-5 and KIT-6 with the aperture being from 2nm to 50nm; and the active ingredients contain one or more elements selected from the group consisting of Co, Fe, Ni, Mn, Cr, Ti, Cu, Mg, Nb, Ta, Mo, W, Zn, Zr, Ru, Ag, Au, Ru, Rh, Pt, Re, Al, W, Ga, Ge, Sn, Sb and metal oxide thereof. The catalyst with meso pore characteristics can be applied to the catalytic purification of tail gases containing nitrogen oxide. The catalyst provided by the invention has high catalytic activity and is suitable for a plurality of pollutants; in addition, the active ingredients of the catalyst are fixed so as to avoid loss, volatilization and high-temperature sintering.
