Topics in Catalysis Aims and scope Submit manuscript

The present study deals with the mechanism of the conversion of NO x and soot into N2 and CO2 on Fe2O3 catalyst. The results of TPO, TRM, DRIFTS and HRTEM examinations suggest a mechanism, in which NO is reduced by dissociation on active carbon sites leading to the formation of N2 and surface oxygen groups. The role of the catalyst lies in the activation of the soot by transferring oxygen from Fe2O3 to soot surface.
