Ultralow loading of nanostructured Mn species onto two-dimensional Co3O4 nanosheets for selective catalytic reduction of NOx with NH3

Abstract

We report a facile method for dispersing Mn species onto two-dimensional Co3O4 nanosheets at the nanoscale for the selective catalytic reduction (SCR) of NOx with NH3. In comparison with the reference catalysts with higher Mn loadings, the Mn/Co3O4 (0.8 wt%) catalyst exhibits improved catalytic activity and a high H2O-resistance ability. Due to the strong interaction between cobalt and manganese oxides and the increased surface area of the Co3O4 nanosheets, the catalyst with an ultralow amount of Mn at the nanoscale possesses stronger reducibility, abundant Co3+ and surface oxygen species, which in turn enhance the NH3-SCR activity.
