The Effects of Morphology of Au/TiO2 Nanoparticle for Photocatalytic Degradation of Methylene Blue |
| 초록 |
Metal-metal oxide core-shell nanoparticles (NPs) have obtained a great deal of attention in photocatalysis because they can combine the photocatalytic function of metal oxide and plasmonic function of metal NPs. In this regard, we synthesize various Au@TiO2 NPs to investigate the effects of their morphologies on the plasmon-assisted catalytic activities. The Au@TiO2 core-shell NPs were synthesized by controlled hydrolysis of TiO2 precursor around the surface of Au NPs. During the synthesis of TiO2 shell, we attempted to adjust the number and the size of Au NPs inside the shell, which eventually lead to interesting materials properties in photocatalytic reaction. By illuminating the synthesized Au@TiO2 NPs with different-colored light, we investigated the synergistic effect of Au and TiO2 on the degradation kinetics of methylene blue. |
