In this present study, tetragonal manganese oxide (Mn 3 O 4 ) nanoparticle was successfully prepared using Mn(CH 3 COO) 2 ⋅4H 2 O as raw material by the ultrasound‐assisted ball milling at a low temperature. The as‐prepared Mn 3 O 4 was characterized by XRD, SEM and N 2 absorption‐desorption. The research results confirmed that the ball milling product was single phase Mn 3 O 4 . The catalytic activity of the as‐prepared sample was testified by quantifying the degradation of the Methyl blue and Rhodamine B aqueous solution with the assistance of H 2 O 2 . It shows the degradation efficiency of Mn 3 O 4 nanoparticle can reach up to 100% within 40 min and 50 min for the Methyl blue and Rhodamine B respectively.
