Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides

Kasongo Wa Kasongo, Jean B.University of the Western Cape2011

In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different oxidation number. Only a single metallic phase catalyst could be prepared …
