Abstract Composite photocatalysts composed of semiconductor and carbon-based materials with non-metal doping have drawn the attention of researchers recently due to their remarkable catalytic and recyclable activities under visible light irradiation. In this study, a novel Bi2MoO6/N-rGO composite was successfully fabricated by a solvothermal method and well-characterized by various instrumental techniques. The Bi2MoO6/N-rGO catalyst exhibited superior photocatalytic performance towards the degradation of dyes compared to bare Bi2MoO6 and Bi2MoO6/rGO catalysts in the presence of visible, UV and solar light irradiations. Such a high photocatalytic performance could be attributed to the enhanced optical absorption property and charge separation efficiency of the composite. The synthesized Bi2MoO6/N-rGO catalyst retained stable photocatalytic performance even after four successive runs. The O2− and h+ influence the photocatalytic degradation of organic compounds catalyzed by Bi2MoO6/N-rGO composite. A possible photocatalytic mechanism was proposed for the improved photocatalytic activity.

用于高效光催化降解有害染料的新型 Bi2MoO6/N-rGO 催化剂的制备

摘要 由半导体和碳基材料与非金属掺杂组成的复合光催化剂由于在可见光照射下具有显着的催化和可回收活性，近年来引起了研究人员的关注。在这项研究中，通过溶剂热法成功制备了一种新型 Bi2MoO6/N-rGO 复合材料，并通过各种仪器技术对其进行了表征。在可见光、紫外线和太阳光照射下，与裸 Bi2MoO6 和 Bi2MoO6/rGO 催化剂相比，Bi2MoO6/N-rGO 催化剂对染料降解表现出优异的光催化性能。如此高的光催化性能可归因于复合材料增强的光吸收性能和电荷分离效率。合成的 Bi2MoO6/N-rGO 催化剂即使在连续四次运行后仍保持稳定的光催化性能。O2− 和 h+ 影响 Bi2MoO6/N-rGO 复合材料催化的有机化合物的光催化降解。提出了一种可能的光催化机制来提高光催化活性。
