 Abstract
PDF
Pt has been widely used as catalyst for fuel cell and exhausted gas clean systems due to its high catalytic activity. Recently, there have been researches on fabricating composite materials of Pt as a method of reducing the amount of Pt due to its high price. One of the approaches for saving Pt used as catalyst is a core shell structure consisting of Pt layer on the core of the non-noble metal. In this study, the synthesis of Pt shell was conducted on the surface of TiO2 particle, a non-noble material, by applying ultraviolet (UV) irradiation. Anatase TiO2 particles with the average size of 20~30 nm were immersed in the ethanol dissolved with Pt precursor of H2PtCl6∙6H2O and exposed to UV irradiation with the wavelength of 365 nm. It was confirmed that Pt nano-particles were formed on the surface of TiO2 particles by photochemical reduction of Pt ion from the solution. The morphology of the synthesized Pt@TiO2 nano-composite was examined by TEM (Transmission Electron Microscopy). -
