제목 | Fabrication of TiO2 macroporous films loaded with Pt used for enhanced photocatalyst |
초록 | Titanium dioxide (TiO2) is used as a photocatalyst in such processes as industrial wastewater treatment since it is a large-band-gap semiconductor with a catalytically active surface. For enhancing photocatalytic activity, macroporous structure, which has a larger active surface, is effective. Furthermore, modification of TiO2 structures such as introducing small amounts of noble metal can increase the activity of TiO2 even under visible light. In this study, we have synthesized the TiO2 macroporous films loaded with platinum (Pt) nanoparticles. Pt/TiO2 nanocomposite films were fabricated mainly by two steps: (i) Prepared in the TiO2 macroporous films through dip coating process via modified sol-gel method using PS colloidal template; (ii) On TiO2 macroporous films, Pt nanoparticles were loaded using H2PtCl6 solution. This Pt/TiO2 nanocomposite films were used for enhanced photocatalyst. |
