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.

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.
