| 1 | Efficient photo-assisted Fenton oxidation treatment of multi-walled carbon nanotubes显示文摘In this paper,a new and efficient way to oxidize and functionalize the multi-walled carbon nanotubes (MWNTs) has been developed by using a combination of ultraviolet (UV) irradiation and Fenton oxida-tion process,namely UV/Fenton oxidation treatment. Comparing with conventionally individual Fenton oxidation treatment of MWNTs,UV/Fenton combined treatment improved the etching rates and effi-ciencies and hence reduced the time for surface modification of MWNTs,which was proved to be an effective method in etching and functionalizing CNTs. The formation of new functional groups,struc-tural changes and thermal stability during oxidation period were characterized by Fourier transform infrared spectroscopy (FTIR),Raman spectroscopy and could be clarified by thermogravimetric analy-sis (TGA),which showed that it was under UV irradiation conditions that MWNTs could be rapidly functionalized with hydroxyl,carbonyl and carboxyl groups in the presence of Fenton reagents,origi-nating from the increase in the gross HO· concentration and the existent synergetic effect when using UV irradiation combing with Fenton oxidation process. Introduction of such new oxygen-containing functional groups was attributed to attacks of HO· on defect sites and unsaturated bonds of C=C in the MWNTs sample,which should play an important role in accounting for the FTIR and Raman spectral changes. | FAN CaiLing LI Wei LI Xin ZHAO ShiJu ZHANG Ling MO YuJun CHENG RongMing | 2007 | Chinese Science Bulletin2007，52，15： | 4 |

| 8 | The molecular orientation of PNB A on silver nanoparticles显示文摘The molecular orientations of p-nitrobenzoic acid (PNBA) on the surface of silver nanoparticles and silver mirror have been investigated by using surface enhanced Raman scattering (SERS) and UV-visible absorption spectroscopy. In the mixed system of silver colloid/PNBA/ethanol, the orientation of PNBA on silver nanoparticles remarkably different from that on silver mirror was observed, and it mainly resulted from the cooperation effect of the adsorption to surface active sites on silver under the pressure of aqueous molecules. This result is of some significance for further studying surface-interfacial structures and properties of silver nanoparticles, and the technique used in this note is feasible to get the SERS spectra of some molecules insoluble in aqueous solution. | Lijun Guo Juanjuan Yu Yuncai Li Yuzong Gu Yabin Huang Yujun Mo | 2000 | Chinese Science Bulletin2000，45，16： | 0 |
