摘要：
A C3N4-sensitized TiO2 nanotube array-based photoanode was designed and fabricated via the in situ growth of C3N4 on the surface of TiO2 nanotubes. It shows stable and significantly improved PEC activity for hydrogen generation under visible light irradiation with a hydrogen production rate of about 19.1 mu mol h(-1) (a Faradaic efficiency of nearly 100%).
