| 1 | SYNTHESIS OF HYDROPHILIC ZnS NANOCRYSTALS AND THEIR APPLICATION IN PHOTOCATALYTIC DEGRADATION OF DYE POLLUTANTS显示文摘Hydrophilic ZnS nanocrystals with narrow size distribution were synthesized via homogeneous precipita- tion using EDTA as stabilizer. The as-synthesized products were characterized with XRD, TEM, HRTEM and UV-Vis spectrum. UV-Vis spectra showed that ZnS nanocrystals exhibited strong quantum-confined effect with a blue shift in the band gap of light absorbance. The photocatalytic activity of these nanocrystals was also investigated for the liquid phase photocatalytic degradation of Basic Violet 5BN (BV5) dye under UV irradiation. It was found that the ZnS nanocrystals had good catalytic activity for photodegradation of BV5. | JunpingLi YaoXu YongLiu DongWu YuhanSun | 2004 | China Particuology2004，2，6： | 5 |
