Abstract A novel nitrogen doped carbon dots (N-CDs) modified CuBi2O4 photocatalyst was prepared through a facile hydrothermal method, and applied to the photocatalytic water splitting under visible light irradiation (λ > 400 nm). Results exhibited the increased photocatalytic hydrogen production of N-CDs/CuBi2O4 compared with pure CuBi2O4 and CDs/CuBi2O4. The excellent photocatalytic performance of N-CDs/CuBi2O4 composite was attributed to efficient synergistic effect between N-CDs and CuBi2O4, which increased light harvesting and electron transfer capacity. Additionally, a possible photocatalytic mechanism of N-CDs/CuBi2O4 composite was proposed.

在新型氮掺杂碳点/CuBi2O4 微棒复合材料上增强可见光驱动的光催化析氢

摘要 通过简便的水热法制备了一种新型氮掺杂碳点(N-CDs)修饰的CuBi2O4光催化剂,并将其应用于可见光(λ> 400 nm)照射下的光催化分解水。结果表明,与纯 CuBi2O4 和 CDs/CuBi2O4 相比,N-CDs/CuBi2O4 的光催化产氢量增加。N-CDs/CuBi2O4 复合材料优异的光催化性能归因于 N-CDs 和 CuBi2O4 之间的有效协同作用,提高了光收集和电子转移能力。此外,还提出了 N-CDs/CuBi2O4 复合材料可能的光催化机理。
