The transition metal oxide catalyst CuO-MnO2-CeO2 /13X was prepared by the impregnation method． The structure，
compositions and thermal stability of the catalysts were characterized by N2 adsorption /desorption，SEM，XRD and TGA． The
catalytic degradation property of CuO-MnO2-CeO2 /13X for naphthalene was investigated in a fixed catalyst bed． BET analysis
showed 6%CuO-MnO2-2%CeO2 /13X catalyst’s specific surface area was 476 m2 /g and its average pore size was 2. 314 nm．
XRD and SEM results showed that CuO，MnO2 and CeO2 at 13X surface was highly dispersed state under certain load rate，
which could improve the catalytic activity of catalysts． Experimental results indicated that adding appropriate amount of cocatalyst
CeO2 could improve the performance of the catalysts． The catalytic rate of naphthalene reached 65% when the catalyst
load factor was 6%CuO-MnO2-2%CeO2 ．
