Physical Properties and Photocatalytic Activity of Fe- and Co-Doped ZnO Nanoparticles Synthesized via Surfactant Modified Co-Precipitation

Abstract:

Fe- and Co-doped ZnO with various doping concentrations have been synthesized by co-precipitation method in the presence of sodium dodecyl sulfate as anionic surfactant. The obtained sample powders were characterized by X-ray diffraction, Fourier transform infrared absorption, UV-visible diffuse reflectance spectroscopy, electron spin resonance spectroscopy and Brunauer-Emmet-Teller (BET) method. The photocatalytic activity was evaluated by observing the decolorization of methylene blue under UV light irradiation. The results revealed that the addition of a dopant atom significantly enhanced the photocatalytic activity.
