Photocatalytic activity of cobalt-doped Cd1-xAl0.2Fe1.8O4 (0,0.3) spinel ferrite for atrazine degradation
This study investigated the photocatalytic degradation of atrazine using cobalt-doped Cd1-xAl0.2Fe1.8O4 spinel ferrites. Cobalt doping significantly enhances the structural, optical, and photocatalytic properties of ferrites, leading to improved atrazine degradation efficiency. Characterization techniques revealed that Co doping reduced the bandgap, increased the surface area, and altered the particle morphology. The Co0.3Cd0.7Al0.2Fe1.8O4 catalyst achieved 97.21% atrazine degradation within 60 min under the following conditions: pH 7, catalyst dosage 20 mg/L, atrazine concentration 10 ppm, temperature 30 °C, and light intensity 100 W. Cobalt doping reduced the bandgap from 2.5 eV for undoped Cd1-xAl0.2Fe1.8O4 to 2.0 eV Scavenger studies indicated that hydroxyl radicals and superoxide radicals are the primary reactive oxygen species involved in atrazine degradation. These findings demonstrate the potential of cobalt-doped Cd1-xAl0.2Fe1.8O4 spinel ferrites as photocatalysts for the effective removal of atrazine from water.
