| 摘 要： | 该文利用毛细管作用和还原气氛处理相结合的方法,以TiO2纳米颗粒为原料制备了贵金属Pt纳米颗粒填充的TiO2-Pt同轴纳米管复合材料,并对其形貌和结构进行了表征。然后在紫外光源的照射下对甲基橙进行光催化降解实验,光催化实验结果表明该复合纳米材料具有比TiO2纳米颗粒更高的光催化降解甲基橙的催化活性。

| Abstract: | The Co-axis TiO2-Pt nanotubes were prepared by inserting Pt nanoparticles into H2Ti3O7 nanotubes using capillary action and subsequently annealing at reduction atmosphere.The morphologies and structure were characterized by TEM,XRD,and EDX.The photocatalysis results show that the as prepared nanotubes have higher photocatalytic activities in degradation of methyl orange than that of TiO2 nanoparticles. |
