Ag co-doped Fe/ZnO nanoparticles for efficient photocatalytic degradation of Congo red under solar light
Source abstract
Abstract
This study focused on enhancement of ZnO nanoparticle properties by doping Fe3⁺ ions and co-doping with Ag nanoparticles (Ag co-doped Fe/ZnO) via sol–gel technique. XRD confirmed Fe3⁺ integration into ZnO wurtzite lattice, suppressing crystallinity, while Ag formed cubic structures on Fe/ZnO surfaces. Morphological analysis revealed homogeneous Ag nanoparticles (4–12 nm) distributed on agglomerated spherical Fe/ZnO. Optical analysis showed a narrowed band gap, shifting absorbance from UV (ZnO) to visible regions (Ag co-doped Fe/ZnO). Antimicrobial tests againstE. colidemonstrated a three times larger inhibition zone for Ag co-doped Fe/ZnO compared to ZnO, which could be attributed to Ag distribution. Congo red photodegradation efficiency reached 99% for Ag co-doped Fe/ZnO versus 36% for ZnO, linked to enhanced generation of•O₂¯ and•OH radicals. The synergistic effects of Fe3⁺ doping and Ag co-doping significantly boosted photocatalytic and antibacterial performance making it as a promising composite for environmental and biomedical applications.Graphical abstract
