| 目的 将通常不适用于颗粒基底的磁控溅射方法应用于纳米颗粒基底，以探索简单、快速、无污染的纳米颗粒表面负载金属新方法。方法 采用往复摆动样品台和变频振动发生器，将二氧化钛纳米颗粒充分分散，用磁控溅射方法在其表面负载了金属金纳米点，并初步研究了不同溅射功率对实验结果的影响。借助扫描电子显微镜（SEM）、透射电子显微镜（TEM）与X射线光电子能谱分析（XPS）对所制备的纳米复合颗粒进行了形貌、结构和成分表征。结果 使用磁控溅射方法，在平均粒径为21 nm的二氧化钛颗粒表面成功负载了粒径约1~10 nm的金属金纳米点，其分布均匀，与基底产生了紧密结合。结论 磁控溅射方法可以应用于纳米颗粒表面负载金属。 |
| 英文摘要: |
| The work aims to develop a new, simple, fast and pollution-free approach to load nanoparticles with metal nanodots by applying magnetron sputtering method which is conventionally unsuitable for particle substrate to nanoparticle substrate. TiO2 nanoparticles were fully dispersed with reciprocating sample stage and variable frequency vibration generator. Au metal nanodots were loaded on the surface by magnetron sputtering method. Effects of different sputtering power on experimental results were primarily studied. Surface morphology, structure and composition of the nano composite particles were characterized by using scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS). Uniformly distributed Au metal nanodots with particle size of 1~10 nm were successfully loaded on the surface of TiO2 nanoparticles with average particle size of 21 nm by magnetron sputtering method. The nanodots exhibited close bonding to the substrate. Magnetron sputtering method can be utilized to load nanoparticles with metal nanodots. |
