Abstract

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

摘要

MnO-CuO-FeO/CNTs催化剂作为一种低维材料，通过温和的氧化还原策略制备，并用于脱硝反应。提出了该催化剂的形成机理。4% MnO-CuO-FeO/CNTs催化剂在80-180°C下的NO转化率达到43.1-87.9%，这归因于非晶态MnO、CuO和FeO的生成以及高表面氧（O）含量。
