Abstract
Improved photocatalytic activity through cobalt (Co) doping has been reported for Al2O3 nanoparticles in this paper. Undoped and Co-doped Al2O3 nanoparticles have been synthesized via a precipitation method. Pure and Al2O3 nanoparticles exhibit a monoclinic crystal structure. The optical bandgap decreases from 3.80 eV to 3.64 eV with Co doping. Due to the red shift in the bandgap, the recombination rate of photo-induced electrons and holes decreases in the doped catalysts which improved their efficiencies against the degradation of rhodamine dye. A remarkable degradation efficiency of 95.45% is evinced for the 4 wt.% Co-doped Al2O3 catalyst and this was well acknowledged from its decreased crystallite size, decreased bandgap and increased photosensitivity values. An increased degradation rate constant value of 0.96649 min−1 observed for the 4 wt.% Co-doped Al2O3 catalyst also confirms this. The results obtained indicate that the Co-doped Al2O3 nanoparticles are potential candidates as visible light catalysts with remarkable degradation efficiencies against toxic dyes. Also, the realization of ferromagnetism confirms the regenerable and reusable quality of the Co-doped Al2O3 catalysts.
