Abstract

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 μmol h⁻¹ (a Faradaic efficiency of nearly 100%).
