Structure, characterization, and dynamic performance of a wet air oxidation catalyst Cu-Fe-La/α-Al2O3
(CFLA) catalyst was prepared by the excessive impregnation method and characterized by scanning electron microscopy
transmission electron microscopy
X-ray diffraction
and X-ray photoelectron spectroscopy. The results indicate that the catalyst contained mostly Cu
2+
Fe
3+
and La
3+
and a small amount of Cu

Fe
2+
and La. The active components were uniformly distributed in the catalyst
and the particle size of the components was approximately 7.5 nm. The CFLA catalyst was used for the treatment of methyl orange (MO) solution by catalytic wet air oxidation (CWAO)
and it exhibited a high catalytic activity. The catalytic reaction involved variable valence states of metals and free-radical reaction mechanism. The CWAO reaction of MO solution was fitted by a segmented first-order dynamic model
and the rapid reaction apparent activation energy was 13.9 kJ·mol
