通过在TiO 2纳米管表面原位生长C3 N4，设计并制备了C3 N4敏化TiO 2纳米管阵列光阳极。在可见光照射下，PEC的产氢活性稳定且显著提高，产氢速率约为19.1 μmol·h（-1）（法拉第效率接近100%）。
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%).
