Synthesis of MnO 2 -CuO-Fe 2 O 3 /CNTs catalysts: low-temperature SCR activity and formation mechanism

MnO -CuO-Fe O /CNTs catalysts, as a low-dimensional material, were fabricated by a mild redox strategy and used in denitration reactions. A formation mechanism of the catalysts was proposed. NO conversions of 4% MnO -CuO-Fe O /CNTs catalyst of 43.1-87.9% at 80-180 °C were achieved, which was ascribe...

Zusammenfassung:MnO -CuO-Fe O /CNTs catalysts, as a low-dimensional material, were fabricated by a mild redox strategy and used in denitration reactions. A formation mechanism of the catalysts was proposed. NO conversions of 4% MnO -CuO-Fe O /CNTs catalyst of 43.1-87.9% at 80-180 °C were achieved, which was ascribed to the generation of amorphous MnO , CuO and Fe O , and a high surface-oxygen (O ) content.
