Abstract


Due to intrinsic properties of graphene-like high electrical conductivity and large surface area, these properties make it an attractive matrix for composites. In this work, reduced graphene oxide (RG)/Fe3O4 (M)/Ag2CO3 (S) hybrid nano-composite (MRGS) has been effectively produced by coprecipitation techniques. The prepared composites were investigated by powder X-ray diffraction (XRD), Fourier transforms infrared spectra (FT-IR), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectra (UV-vis/DRS), Raman and vibrating sample magnetometer (VSM). The prepared MRGS nano-composite shows significant enhancement in the degradation rate of Tartrazine dye (TZ) compared to commercial photo-catalyst such as TiO2. Meanwhile, the visible light absorption of the MRGS nano-composite is progressively refining with the increase of the percentage of Ag2CO3 on the surface of (RG). The obtained MRGS 75 photo-catalyst shows the best photo-catalytic activity for TZ under visible light irradiation. The close contact between Ag2CO3 and RG in the composite leads to accelerating the charge transfer on Ag2CO3 to RG and thus enhancing the photocatalytic activity. Additionally, the prepared composite displays superb separability and significant stability.  © VBRI Press.
