采用紫外光輻照不同氧化劑體系對碳微球（CMSs）表面進行化學修飾，引入含氧官能團以改善其表面惰性。利用場發(fā)射掃描電子顯微鏡對樣品進行形貌分析，通過紅外光譜、熱重分析、X射線光電子能譜和酸堿滴定法對處理后樣品表面的含氧官能團進行定性和定量分析，并觀察了氧化后CMSs在乙醇中的分散性。結(jié)果表明：UV輻照下3種氧化體系（H2O2 ，H2O2+HNO3，H2O2+H2SO4）修飾的CMSs表面均引入了含O官能團；相對而言，UV/H2O2+H2SO4體系氧化處理的CMSs表面引入的含氧官能團總量最多，這為碳材料提供了一種新型高效的氧化技術(shù)。
- Abstract:

Carbon microspheres (CMSs) were modified to improve their surface activity using different oxidant systems under ultraviolet (UV) irradiation. The morphologies of all samples were characterized by field emission scanning electron microscopy, and the functional groups introduced onto the surface of CMSs were analyzed qualitatively and quantitatively by Fourier transformation infrared spectrometry, thermogravimetry, Xray photoelectronic spectrometry and acidbase titration. The dispersion of oxidized CMSs in ethanol was also observed. The results show that oxygencontaining groups were introduced onto the surface of CMSs in the three oxidative systems (H2O2, H2O2/HNO3, H2O2/H2SO4) under UV irradiation. The CMSs oxidized by UV/H2O2+H2SO4 showed the most amounts of oxygencontaining groups, which give a efficient method to oxidize carbon materials.
