Abstract

The catalytic combustion of benzene over a Ni-Mn mixed oxide supported on cordierite coated with CeO₂ was investigated. The catalysts were prepared using a sol-gel method and characterized using BET, H₂-TPR, XRD, SEM and TEM. The catalysts calcined at 500°C for 7h with a Ni/Mn molar ratio of 1 exhibited the highest catalytic activity. When the concentration of benzene was 4.8g/m³ and the GHSV was 15,000h^-1, the conversion was 94.3% at 300°C. These results were primarily attributed to the catalyst structure and the synergistic activity of the NiMnO₃ perovskite and crystalline CeO₂.
