摘要/Abstract

摘要：

不采用任何模板, 利用原位逐步水热方法一次性合成了花状Cu2O/Cu复合材料. 采用X射线衍射、扫描电镜、高分辨透射电镜和自动吸附仪对样品的相结构、形貌和比表面积进行了表征. 以偶氮染料Procion Red MX-5B为探针分子, 对复合催化剂进行了可见光催化表征. 结果表明该复合催化剂中的Cu和Cu2O之间存在相互作用, 其催化活性远高于单相Cu2O和商用P25粉末, 有望成为污水治理的新型材料.

Abstract:

Cu2O/Cu nanocomposites with flowerlike nano-architecture were prepared using a template-free two-step hydrothermal synthesis route. The phase-structure, morphology and specific surface area were characterized by the X-ray differction(XRD), scanning electron microscope(SEM), high resolution transmission electron microscope(HRTEM) and automatic adsorption. The photocatalytic property of the composite catalyst was characterized by phtodegradation on Procion Red MX-5B under visible-light illumination. Compared with Cu2O and P25, the flowerlike Cu2O/Cu nanocomposites exhibit higher photocatalytic performance on photodegradation of Procion Red MX-5B under visible-light illumination due to the interaction between Cu2O and Cu, indicating that they are good candidates for the processing of pollutants.

Key words: Cu2O/Cu; Heterostructure; Nanoflower; Photocatalysis; Photodegradation of procion Red MX-5B
