摘要:
 利用化学气相沉积法，制备了直径约370 nm的碳微球（CMSs）；然后用浓HNO3和H2O2对其进行氧化修饰，使其表面接上羟基等含氧官能团；最后再与醋酸锌和三乙醇胺反应，在CMSs表面包覆ZnO层形成ZnO/CMSs复合物，在此过程中考察了醋酸锌和三乙醇胺物质的量比和反应时间对复合物的影响。采用场发射扫描电子显微镜、红外光谱、热重分析仪和X射线衍射仪等对各阶段产物进行了形貌和结构的表征与分析。结果表明：醋酸锌和三乙醇胺的物质的量比为1 2，反应时间为2 h时，得到的ZnO/CMSs复合物外观形貌光滑，包覆均匀且不易脱落。
Abstract:
 Carbon microspheres (CMS) with size of 370 nm were synthesized by chemical vapor deposition. Then CMSs were oxidized with a mixture of concentrated HNO3 and H2O2 Finally, CMSs were covered with ZnO to form ZnO/CMS composites after CMSs were reacted with zinc acetate and triethanolamine. The influences of molar ratio of zinc acetate to triethanolamine and reaction time were investigated. The morphology and structure of the products were characterized by field emission scanning electron microscopy, Fourier transformation infrared spectrometry, thermogravimetry and Xray diffraction. The results show that the obtained ZnO/CMS composites with uniform size had smooth surfaces and the interaction between ZnO and CMSs was stronger when the molar ratio of zinc acetate to triethanolamine was 1 2 and the reaction time was 2 h.
