Synthesis and Characterization of Fe2(MoO4)3 Nano-Photocatalyst by Simple Sol–Gel Method
Ferric molybdate (Fe2(MoO4)3) nanorods (NRs) were successfully synthesized using metal nitrates, citric acid and ethyl cellulose by a simple sol–gel method. Structural, morphological, optical and magnetic properties of the obtained powder were characterized by powder X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra, high resolution scanning electron microscope (HR-SEM), energy dispersive X-ray (EDX), UV-Visible diffuse reflectance spectra (DRS), photoluminescence (PL) spectra and vibrating sample magnetometer (VSM). XRD results indicated that the resultant powder was pure single phase crystalline with monoclinic structure. FT-IR spectra indicate the type of bonds between metals and oxygen. HR-SEM images shows that the morphology of the powder consist with well defined nanorods (NRs) structure. VSM results showed ferromagnetic behavior. The addition of TiO2 catalyst, it enhanced the photo-catalytic activity of Fe2(MoO4)3. The mixed oxide catalyst of Fe2(MoO4)3–TiO2 nano-composites (NCs) were also tested for the photocatalytic degradation (PCD) of 4-chlorophenol (4-CP). It was found that the PCD efficiency of Fe2(MoO4)3–TiO2 NCs is higher than pure Fe2(MoO4)3 and TiO2 catalysts.
