Photochemical systems have been widely studied and applied to various research areas such as environmental remediation and solar energy conversion. In this study, it will be briefly summarized applications of nafion to photochemical systems. Nafion, a cation-exchange perfluorinated polymer with sulfonate functional groups, is chemically and photochemically inert, and it can be utilized as a stable immobilizing agent. First, nafion-coated TiO2 particle (Nf/TiO2) was applied to environmental treatment of organic pollutants under UV or visible light. Second, Nf/TiO2 with platinum nano-metal deposit was used for visible light-sensitized hydrogen production. Finally, Ru(bpy)32+-based homogeneous hydrogen production system was immobilized in nafion matrix and studied. Theses applications of Nafion not only enhance photochemical conversion efficiencies but also uniquely affect photochemical behaviors. |
