Abstract
Manganese and iron oxides on alumina prepared by two-nozzle flame synthesis show improved CO-oxidation activity due to minimized composite formation.
Highlights
Diesel oxidation catalysis (DOC) is one of the major technologies in exhaust gas aftertreatment systems of lean burn engines to oxidize pollutants, such as CO, non-combusted hydrocarbons and the organic fraction of diesel particulates, to harmless exhaust gas products.[1]
We have systematically investigated the use of double-flame spray pyrolysis for the preparation of Mn/Al2O3 and Fe/Al2O3 catalysts in comparison to singleflame spray pyrolysis
Mn-based catalysts prepared with DF show a BET surface area of about 90 m2 g−1 which is almost constant for all loadings
Summary
Diesel oxidation catalysis (DOC) is one of the major technologies in exhaust gas aftertreatment systems of lean burn engines to oxidize pollutants, such as CO, non-combusted hydrocarbons and the organic fraction of diesel particulates, to harmless exhaust gas products.[1]. Iron oxide nanoparticles were found to exhibit high catalytic activity for CO, CH4, and C3H6 oxidation.[18]
