Abstract Scope |
We present a highly efficient method for a catalytic breakdown of organic compounds using unique magnetoelectric nanorods inside hollow-nanosphere. The nanostructure is fabricated in a single-step process using Ultrasonic Spray Pyrolysis. Furthermore, the study investigates the catalytic degradation of organic pollutants using magnetoelectric nanostructure under AC magnetic field excitation, achieving an unprecedented 85% removal efficiency for synthetic dyes. This efficiency is attributed to surface redox reactions facilitated by the transfer of electrons and holes, leading to the generation of reactive oxygen species such as O2.-and .OH. Additionally, the magneto-catalytic activity of the system demonstrates a 95.9% and 99.9% reduction in Escherichia coli and Staphylococcus Aureus bacteria, respectively, after 90 minutes of exposure to a 20 mT and 2 kHz AC magnetic field. The synergistic interaction between nanorod at core with hollow-nanosphere shell makes a magnetoelectric nanoscale device capable of purifying water through advanced oxidation processes under remotely controlled magnetic fields. |
