| Tóm tắt: | Заглавие с экрана In the present study, the catalytic activity of biocompatible magnetoelectric (ME) core-shell nanoparticles (NPs) based on MnFe2O4 (MFO) and Ba0,85Ca0,15Zr0,1Ti0,9O3 (BCZT). ME NPs were formed via hydrothermal method. Rhodamine B was used a model dye. Prior to BCZT shell formation, magnetostrictive cores were functionalized with oleic acid (OA) or polyvinylpyrrolidone (PVP). The solution with the dye and nanoparticles of different concentrations was exposed to an alternating magnetic field with an amplitude of 150 mT and a frequency of 100 Hz. The efficiency of the model dye degradation reached more than 50% after 1 hour of exposure with magnetoelectric nanoparticle concentrations of 4 mg/ml and 8 mg/ml. Nanoparticles based on PVP-functionalized MFO cores showed more effective catalytic activity compared to NPs based on the OA-functionalized MFO cores. Текстовый файл |
