| 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 wit... |
