氧化锌空心球的制备及其光催化性能研究

Study on Preparation and Photocatalytic Activity of ZnO Hollow Spheres

以葡萄糖、尿素和醋酸锌为原料在低温下合成了炭微球,高温煅烧后制备了氧化锌空心微球。通过X-射线衍射(XRD)、扫描电子显微镜(SEM)等手段对制得的样品进行了表征。以甲基橙溶液为研究对象考察了氧化锌空心微球的光催化性能。实验结果表明,当葡萄糖和醋酸锌质量比为3∶1时,制备的ZnO微球具有较好的光催化性能。

Carbon microspheres were successfully synthesized by using glucose,urea and zinc acetate as the raw materials at low-temperature,and zinc oxide hollow microspheres were fabricated after calcination.The samples obtained was characterized by X-ray diffraction（XRD）,scanning electron microscopy（SEM）.Effect of ZnO microspheres as photocatalyst on degradation of methyl orange was investigated.The results showed that the ZnO microspheres synthsised had good photocatalytic activity when the ratio of glucose to zinc acetate was 3∶ 1.
