Synthesis of heterojunction nanocomposites ZnFe2O4/ZnO/Nb2O5 for photocatalytic, capacitor and antibacterial applications

Deriving the heterojunction nanocomposite for multifunction applications has attracted interest. Herein, we synthesized the ZnFe2O4/ZnO/Nb2O5 heterojunction nanocomposite by varying the Nb2O5 concentration from 0.03 to 0.07 mol% by the facile combustion method and analyzed its characteristics properties. Powdered X-ray diffraction (PXRD), spectrum from Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), ultraviolet (UV) visible spectrophotometer, and Energy dispersive X-ray (EDX) analysis experimented to investigate the structure, optical properties, morphological nature and photodegradation performance of the heterojunction nanocomposites. PXRD was employed to investigate the composite's crystallinity formation. The morphology from the SEM image gives the flowed bud structure with confirmed crystallinity. The prepared ferrite as photocatalyst shows the degradation efficiency of 94 % for the crystal violet dye, as antimicrobial agent showed that the gram -negative bacterium pseudomonas had a better inhibitory zone around them and being as the electrode shows results as better capacitor and sensor.
