我们提出了一个全面的实验和理论研究的电子性质和光催化活性的氮掺杂的TiO 2纳米带。紫外-可见光谱显示，与原始样品相比，氮掺杂纳米带在可见光范围内的吸收增强。在可见光照射下，与原始样品相比，氮掺杂的纳米带表现出改善的光催化活性。此外，氮的掺入在带隙中引入局域态。
We present a comprehensive experimental and theoretical study of the electronic properties and photocatalytic activity of nitrogen-doped anatase TiO2 nanobelts. UV-visible spectra show enhanced absorption in the visible light range for nitrogen-doped nanobelts compared to the pristine sample. The nitrogen-doped nanobelts exhibit improved photocatalytic activity compared to the pristine sample upon visible light irradiation. Furthermore, the incorporation of nitrogen introduces localized states in the band gap.
