Abstract A novel molybdenum dioxide nanosheet/graphene-like carbon nitride (MoO2/GL-C3N4) composite was fabricated by facile solvothermal process. The new-type 2D/2D structured GL-C3N4-based hybrid with compact interfacial contact distinctly showed high and stable performance for the degradation of Rhodamine B (RhB) under visible light irradiation. Meanwhile, sufficient interfaces, plentiful intrinsic active sites and shortened path of electron transport can be provided, which play a vital role in improving separation efficiency of hole-electron pairs, triggering promotional photocatalytic performance of GL-C3N4. Notably, MoO2/GL-C3N4 composites with 2% MoO2 exhibited the highest photocatalytic activity, approximately 4.2 times as high as monomer GL-C3N4. It was the remarkable synergistic effect of Mo N chemical bond between MoO2 nanosheets and GL-C3N4 that highly improved the visible light photocatalytic activity of hybrids for RhB decomposition.

MoO 2 纳米片和类石墨烯C 3 N 4 的协同效应显着提高可见光光催化活性

摘要 采用简便的溶剂热法制备了一种新型二氧化钼纳米片/类石墨烯氮化碳(MoO2/GL-C3N4)复合材料。新型 2D/2D 结构的 GL-C3N4 基杂化物具有紧密的界面接触,在可见光照射下对罗丹明 B (RhB) 的降解表现出高而稳定的性能。同时,可以提供足够的界面、丰富的内在活性位点和缩短的电子传输路径,这对于提高空穴-电子对的分离效率,触发 GL-C3N4 的光催化性能起到至关重要的作用。值得注意的是,含 2% MoO2 的 MoO2/GL-C3N4 复合材料表现出最高的光催化活性,约为单体 GL-C3N4 的 4.2 倍。
