| 摘 要： | 采用水热法,在乙二胺和EDTA-2Na作用下,成功制备了CdS@g-C3N4复合核壳纳米微粒,并探讨了其生长机理。结果显示:CdS@g-C3N4复合核壳纳米微粒的比表面积是纯CdS纳米颗粒的14.0倍,具有良好的光催化活性和光稳定性。当反应条件为180℃、4 h、CdS/g-C3N4质量比1.9∶1时,CdS@g-C3N4的可见光催化性能最好,300 W氙灯光照2 h,RhB的降解率达95.2%,明显高于纯CdS。重复使用3次后,CdS@g-C3N4形貌、结构及光催化性能无明显变化。

| Abstract: | The CdS@g-C3N4 core-shell composite nanoparticles were successfully prepared by a hydrothermal method with the addition of ethylenediamine and EDTA-2 Na.The nucleation and growth mechanism of CdS@gC3N4 was also discussed.The specific surface area of CdS@g-C3N4 core-shell composite nanoparticles was 14 times larger than that of the pure CdS nanoparticles.CdS@g-C3N4,which was prepared under the reaction conditions of 180℃,4 h and 1.9∶1(the mass ratio of CdS to g-C3N4),exhibited the best catalytic performance.The degradation efficiency of RhB with CdS@g-C3N4 composite reached 95.2%after 2 h of irradiation under 300 W xenon,which was significantly higher than that over pure CdS.After three cycles,CdS@g-C3N4 showed no obvious changes in the morphology,structure and photocatalytic performance. |
