| Abstract: |
| 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. |
