| 摘 要： | 对纳米 Ga P粉体 -结晶紫水溶液光催化降解进行了研究。纳米 Ga P粉体在紫外光照射条件下对结晶紫具有光催化降解作用 ;随平均颗粒度的降低 ,纳米 Ga P粉体的光催化活性增加。红外光谱测试结果表明 :进行光催化过程以后 ,纳米 Ga P表面存在的几种主要振动模式变化较小或不变 ;拉曼光谱测试结果表明 :纳米 Ga P粉体的横向光学声子模与纵向光学声子模 ,以及表面主要振动模式几乎没有发生变化

| Abstract: | Under the condition of irradiation with a high pressure mercury lamp,GaP nanoparticles can be employed to carry out heterogeneous photocatalytic process.The photocatalytic activity of GaP nanoparticles increases with decreasing the average size of GaP.The infrared spectra of irradiated GaP nanoparticles show that there is almost no change in the surface structure of GaP before and after the irradiation,and also,the same results are obtained in the Raman spectra of the LO,TO and PO 2. |
