In this article, M-FeO-CuO (M: Mn, Ag and Co) mixed oxides nanocatalysts were synthesized by a novel ultrasound-assisted hydrothermal method and the effect of irradiation power and time on the physicochemical and catalytic properties in oxidation of carbon monoxide at low temperature was investigated. The synthesized samples were studied using XRD, BET, TPR and SEM techniques. The results indicated that the incorporation of Mn into Cu-Fe catalyst had a significant influence on the catalytic properties and the catalyst promoted with 10 wt% Mn exhibited the full conversion of CO at 100 °C. This catalyst possessed a high BET area (145.1 m g) and a mesoporous texture with a relatively narrow pore size distribution with a mean crystal size of 13 nm.
在本文中,通过一种新型超声辅助水热法合成了M-FeO-CuO(M:Mn、Ag和Co)混合氧化物纳米催化剂,并研究了辐照功率和时间对低温一氧化碳氧化中物理化学和催化性能的影响。使用XRD、BET、TPR和SEM技术对合成的样品进行了研究。结果表明,将Mn掺入Cu-Fe催化剂中对催化性能有显著影响,用10 wt% Mn促进的催化剂在100°C时表现出CO的完全转化。该催化剂具有高BET面积(145.1 m²/g)和介孔结构,孔径分布相对较窄,平均晶体尺寸为13 nm。
