Well-ordered TiO₂ nanotube arrays (TNTAs) decorated with graphitic carbon nitride (g-C₃N₄) were fabricated by anodic oxidization and calcination process. First, TNTAs were prepared via the anodic oxidation of Ti foil in glycerol solution containing fluorinion and 20% deionized water. Subsequently, g-C₃N₄ film was hydrothermally grown on TNTAs via the hydrogen-bonded cyanuric acid melamine supramolecular complex. The results showed that g-C₃N₄ was successfully decorated on the TNTAs and the g-C₃N₄/TNTAs served as an efficient and stable photoanode for photoelectrochemical water splitting. The facile deposition method enables the fabrication of efficient and low-cost photoanodes for renewable energy applications.

通过gC进行的高效光电化学水分解3ñ4/钛2个 纳米管阵列异质结构

通过阳极氧化和煅烧工艺制备了装饰有石墨氮化碳（gC ₃ N ₄）的有序TiO ₂纳米管阵列（TNTA）。首先，通过在含有氟离子和20％去离子水的甘油溶液中对Ti箔进行阳极氧化来制备TNTA。随后，通过氢键合的氰尿酸三聚氰胺超分子络合物在TNTA上水热生长gC ₃ N ₄膜。结果表明GC ₃ Ñ ₄被装饰成功对TNTAs和GC ₃ Ñ ₄/ TNTAs是用于光电化学水分解的高效，稳定的光阳极。简便的沉积方法能够制造可再生能源应用中的高效，低成本的光阳极。
