中文摘要：

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ProcionRedMX-SB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．

英文摘要：

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 photo-degradation 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.
