Description
Summary:•Novel MnWO4/TmVO4 ternary nano-hybrids can be prepared by sonochemical method.•MnWO4/TmVO4 ternary nano-hybrids exhibit paramagnetic behavior.•MnWO4/TmVO4 ternary nano-hybrids possess band gap equal to 2.4 eV.•MnWO4/TmVO4 nano-hybrids catalyze degradation of different dyes under visible light. In this study, novel MnWO4/TmVO4 ternary nano-hybrids were synthesized effectively via a simple sonochemical method. The products were characterized in detail with the use of modern analytical techniques including XRD, EDX, TEM, DRS, BET, PL, and VSM. To the authors’ best knowledge, this is the first report on the synthesis and photocatalytic performance of MnWO4/TmVO4 ternary nano-hybrids in the degradation of rhodamine B (Rh B), 2-naphthol (Na), phenol red (Ph R), and eosin Y (EY) under visible light. Based on the degradation results, MnWO4/TmVO4 is shown to have higher photodegradation ability than pure TmVO4 or MnWO4 nanoparticles. It was also found that maximum degradation (99.2%) is achieved in the case of Rh B dye.
