We have focused on titanium dioxide nanotube arrays (TNAs) and graphitic carbon nitride (g-C₃N₄) as photocatalyst materials, and have been working on structural control of TNA/g-C₃N₄ composites by thermal chemical vapor deposition (CVD) toward enhancement of their photocatalytic activity. In this presentation, our fluorescence (PL) measurements using hydroxyl radical trapping agents clarified that the photocatalytic activity of TNA/g-C₃N₄ composites under ultraviolet-visible light irradiation can become superior to that of only TNA, by controlling the deposition amount of g-C₃N₄ on TNA surface.
