▎ 摘  要

The MnCe oxides based catalysts with partially reduced graphene oxide support were synthesized, and the prepared catalyst exhibited high NOx removal characteristics at low temperatures. Generally, the graphene oxide has many functional groups on its surface which enables the enhanced dispersion behavior, whereas, the reduced graphene oxide can provide high specific surface area. In order to exploit the advantages graphene oxide and reduced graphene oxide, partially reduced graphene oxide support was synthesized by impregnating the active materials on graphene oxide and the graphene oxide support was further reduced with thermal reduction process. The prepared catalysts exhibited high NOx removal characteristics of 99% at the temperature range 150-300 degrees C, and further elucidated with TEM, BET, NH3-TPD, H-2-TPR, and XPS analysis. By using the partially reduced graphene oxide support, we can synthesize a catalyst exhibiting high NOx removal efficiency with low content of active materials.
