Abstract

In this study, DCM was chosen as the probe reactant, and a series of catalyst materials were synthesized using the impregnation method. The interplay between active transition metal oxide components and acidic supports was examined via activity testing. The results indicated that the catalysts required exceptional surface acidity and redox properties to degrade DCM. Through screening, three species and supports exhibiting outstanding activity were identified. Among them, Co species displayed excellent oxidizing performance for CO, augmenting the yield of CO₂; Ce species demonstrated remarkable degradation activity for DCM, albeit with weaker CO oxidation capabilities; while zeolite molecular sieves, possessing abundant acid sites and a unique pore structure, were more conducive to the catalytic degradation of DCM.
