Ferrite-based hybrid materials for piezo-photocatalytic water treatment
My PhD research proposes the development of ferrite-based hybrid materials for piezo-photocatalytic water treatment. These multifunctional nanomaterials integrate ferroelectric ferrites, such as bismuth ferrite and spinel ferrites, into heterojunction structures to synergistically harness piezoelectric and photocatalytic effects under mechanical stress and light irradiation. The work focuses on optimizing synthesis via sol-gel and co-precipitation methods, characterizing piezo-responsive properties, and evaluating enhanced pollutant degradation efficiency for sustainable wastewater remediation.
Effects of Cu doping upon structural and photo-catalytic properties of MnFe2O4 of nano particles
I investigated how substituting copper (Cu) into manganese ferrite (MnFe2O4) nanoparticles alters their structure and photocatalytic performance for pollutant degradation in water. In this work, MnFe2O4 nanoparticles doped with different Cu contents were synthesized and characterized to evaluate changes in crystal structure, particle size, and optical properties. The results showed that Cu incorporation modified lattice parameters and morphology, which in turn affected light absorption and charge carrier behaviour. As a consequence, the Cu‑doped samples exhibited enhanced photocatalytic activity compared with undoped MnFe2O4, demonstrating their potential for efficient water treatment applications.
