Abstract

The catalytic oxidation of toluene, chosen as VOC probe molecule, was investigated over Co3O4, CeO2 and over Co3O4–CeO2 mixed oxides and compared with the catalytic behavior of a conventional Pt(1 wt%)/Al2O3 catalyst. Complete toluene oxidation to carbon dioxide and water was achieved over all the investigated systems at temperatures below 500 °C. The most efficient catalyst, Co3O4(30 wt%)–CeO2(70 wt%), showed full toluene conversion at 275 °C, comparing favorably with Pt/Al2O3 (100% toluene conversion at 225 °C).
