通过一种简单、绿色、经济的方法成功地制备了花状氧化锌/银纳米复合材料。在该方法中,首先制备了花状前驱体,然后在500℃下2h焙烧,X射线衍射结果证实了花状前驱体中存在纯的纤锌矿结构和金属银。扫描电子显微镜和透射电子显微镜结果表明,所制得的纳米复合材料很好地继承了前驱体的形态和沉积在纳米复合材料内部的银颗粒。紫外-可见漫反射光谱和光致发光光谱表明,纳米复合材料具有可调的光学性质。值得注意的是,在可见光照射下,氧化锌/银纳米复合材料对亚甲基蓝的降解表现出比纯氧化锌更高的光催化活性。
Flower-like ZnO/Ag nanocomposites were successfully synthesized via a simple, green and cost efficient method. In this method, the flower-like precursor was first prepared and subsequently calcined at 500 °C at 2 h. The XRD results confirmed the presence of pure wurtzite ZnO structure and metal Ag in flower-like precursor. The SEM and TEM results revealed that the obtained nanocomposites well inherited the morphology of the precursor and Ag particles deposited on the inside of the nanocomposites. The UV–vis diffuse reflection and PL spectra showed that ZnO/Ag nanocomposites exhibited tunable optical properties. Noteworthily, ZnO/Ag nanocomposites showed more efficient photocatalytic activity in the degradation of MB than that of pure ZnO under visible light irradiation.
