The core‐shell TiO₂@g‐CN nanorods arrays were constructed directly on fluorine‐doped tin oxide grass using vacuum magnetic filtered arc ion plating. The unique structure combines both advantages from TiO₂ as an effective electron‐transfer layer and graphic carbon nitride (g‐CN) with a proper band gap serving as visible light absorption layer. Under 100 mW/cm² (AM 1.5G) light illumination, the optimal TiO₂@g‐CN produces a photocurrent density of 0.91 mA/cm² at 1.23 V vs reversible hydrogen electrode, which is 2.1 times of the bare TiO₂ (0.43 mA/cm²) obtained at the same potential. The improved photoelectrochemical performance is mainly attributed from the improved charge separation and transport within the heterojunction as well as the enhanced light absorption.

使用改良的物理气相沉积法将TiO2纳米棒与g-CN偶联以实现有效的光电化学水氧化

核壳型TiO ₂ @ g-CN纳米棒阵列是使用真空磁过滤电弧离子镀直接在掺氟的氧化锡草上构建的。独特的结构结合了TiO ₂作为有效的电子传输层和图形氮化碳（g-CN）的优点，并具有适当的带隙作为可见光吸收层。在100毫瓦/厘米²（AM 1.5G）光照明下，最佳的TiO ₂ @ G-CN产生0.91毫安/ cm的光电流密度² 1.23 V相对于可逆氢电极，这是裸露的TiO 2.1倍₂（ 0.43 mA /厘米²）以相同的电位获得。光电化学性能的改善主要归因于异质结内电荷分离和传输的改善以及光吸收的提高。
