CuO-Fe2O3 Nano-powder catalysts prepared by precipitation under nltrasonic radiation
【摘要】 采用超声沉淀法制备了标题纳米粉体催化剂 ,运用 XRD、IR、TEM等技术研究了粉体的组成 ,相结构、颗粒粒径及催化分解 H2 O2 活性 .结果表明 ,将超声辐射引入氧化物催化剂的沉淀法制备过程 ,可显著提高催化剂性能 .文中对其原因作了初步讨论 .
【Abstract】 The title nano-powder catalysts were prepared by precipitation under ultrasonic radiation.The composition, structure, particle size and activity of catalysts for H 2O 2 decomposition were investigated by XRD、IR and TEM. The results show that it could improve the properties of catalysts while ultrasonic radiation was introduced into the process of oxides catalysts prepared by precipitation. and which was discussed in this paper.
