利用化學氣相沉積法，制備了直徑約370 nm的碳微球（CMSs）；然后用濃HNO3和H2O2對其進行氧化修飾，使其表面接上羥基等含氧官能團；最后再與醋酸鋅和三乙醇胺反應，在CMSs表面包覆ZnO層形成ZnO/CMSs復合物，在此過程中考察了醋酸鋅和三乙醇胺物質的量比和反應時間對復合物的影響。采用場發射掃描電子顯微鏡、紅外光譜、熱重分析儀和X射線衍射儀等對各階段產物進行了形貌和結構的表征與分析。結果表明：醋酸鋅和三乙醇胺的物質的量比為1 2，反應時間為2 h時，得到的ZnO/CMSs復合物外觀形貌光滑，包覆均勻且不易脫落。

Carbon microspheres (CMS) with size of 370 nm were synthesized by chemical vapor deposition. Then CMSs were oxidized with a mixture of concentrated HNO3 and H2O2 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 Xray 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.
