The invention relates to a ternary layered compound and a preparation method and application thereof, and belongs to the field of catalysis and environmental protection. The catalyst has a hydrotalcite structure, the molecular formula of the catalyst is [M < 2 + > 1-xM < 3 + > x (OH) 2] < x + > (A < n->) x/n.mH2O, M < 2 + > is Ni < 2 + > and Co < 2 + >, M < 3 + > is Fe < 3 + > and Co < 3 + >, A < n-> is CO3 < 2->, NO3 <->, Cl <->, SO4 < 2-> and PO4 < 3-> anions, and x is 0.2-0.5. The invention further discloses a preparation method of the catalyst, and a precursor of M < 3 + > in the preparation method can be divalent or trivalent metal salt of M < 3 + > and is not limited to trivalent metal salt. The catalyst has excellent ozone catalytic decomposition performance, and can be used for catalytic purification of large-air-volume and high-air-velocity ozone.
