【 摘 要 】

MnO₂–CuO–Fe₂O₃/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% MnO₂–CuO–Fe₂O₃/CNTs catalyst of 43.1–87.9% at 80–180 °C were achieved, which was ascribed to the generation of amorphous MnO₂, CuO and Fe₂O₃, and a high surface-oxygen (O_s) content.
