Abstract

Graphitic carbon nitride as a photocatalyst seeking attention nowadays, due to its thermal stability, band structure, and chemical properties. Herein, we reported a boron sulfur co-doped graphitic carbon nitride (B@S-g-C₃N₄) photocatalyst synthesized by a one-pot thermal polycondensation mechanism. However, it was observed that due to co-doping in native carbon nitride structure the photocatalytic behavior and the band structure enhanced which was capable of fascinating the demand of organic transformations i.e. photocatalytic and charge transfer capability. The synthesized B@S-g-C₃N₄ photocatalyst was characterized by UV–vis DRS, FT-IR, XRD, SEM, EDX, HR-TEM, XPS and electrochemical properties. In addition, the synthesized B@S-g-C₃N₄ photocatalyst is a metal-free carbon nitride photocatalyst proven to be highly effective in performing organic transformations (conversion yield 98 %) like C-N bond formation under visible light source.

熠熠生辉：掺杂 B@S 的氮化石墨碳纳米棒在可见光下催化 C-N 键形成的能力得到增强

氮化石墨作为一种光催化剂，因其热稳定性、能带结构和化学特性而备受关注。在此，我们报道了一种硼硫共掺杂氮化石墨碳（B@S-g-C3N4）光催化剂，该催化剂是通过一锅热缩聚机制合成的。然而，研究发现，由于在原生氮化碳结构中进行了共掺杂，光催化行为和能带结构得到了增强，从而能够满足有机转化的要求，即光催化和电荷转移能力。合成的 B@S-g-C3N4 光催化剂通过紫外-可见 DRS、傅立叶变换红外光谱、XRD、扫描电镜、EDX、HR-TEM、XPS 和电化学特性进行了表征。此外，合成的 B@S-g-C3N4 光催化剂是一种无金属氮化碳光催化剂，在可见光光源下可高效地进行有机转化（转化率达 98%），如 C-N 键的形成。
