摘要

以Mn(II)席夫碱配合物为基料，合成了新型磁性Mn3O4/g-C3N4和Ag2MnO4/g-C3N4纳米复合材料，并用于水溶液中亚甲基蓝(MB)和甲基橙(MO)染料的超声降解。本文首次在超声辐照下，以mn3o4nps和AgNO3为原料合成了Ag2MnO4纳米颗粒。结果表明，在Mn3O4/g-C3N4和Ag2MnO4/g-C3N4纳米复合材料存在下，超声降解染料的方法优于太阳降解方法。Ag2MnO4/g-C3N4 (k= 0.0916 min-1)和Mn3O4/g-C3N4 (k= 0.0381 min-1)对MB和MO染料的光降解率均优于纯Mn3O4和Ag2MnO4，所合成的纳米复合材料是良好的荧光材料。

Mn3O4 and Ag2MnO4 nanoparticles loaded on g-C3N4 as magnetically catalysts for sonodegradation of dyes

New magnetic Mn3O4/g-C3N4 and Ag2MnO4/g-C3N4 nanocomposites have been synthesized based on Mn(II) Schiff base complex and used for sonodegradation of methylene blue (MB) and methyl orange (MO) dyes in aqueous solution. Ag2MnO4 nanoparticles (NPs) have been synthesized from Mn3O4 NPs and AgNO3 under ultrasonic irradiation for the first time. The results indicate that the sonodegradation method of dyes in the presence of Mn3O4/g-C3N4 and Ag2MnO4/g-C3N4 nanocomposites is better than solar degradation processes. The better photodegradation rates for MB and MO dyes observed in the presence of Ag2MnO4/g-C3N4 (k= 0.0916 min-1) and Mn3O4/g-C3N4 (k= 0.0381 min-1), as compared to pure Mn3O4 and Ag2MnO4 compounds The synthesized nanocomposites are good fluorescent materials.
