Synthesis and characterization of Sm2(MoO4)3, Sm2(MoO4)3/GO and Sm2(MoO4)3/C3N4 nanostructures for improved photocatalytic performance and their anti-cancer the MCF-7 cells

Samarium molybdate nanoparticles (Sm2(MoO4)3) were prepared through a hydrothermal procedure and were used to form various composites with graphene oxide (GO) and carbon nitride (C3N4). The changes in the dimensions and morphology of the products were prepared using template agents like cetyltrimethyl ammonium bromide (CTAB), Sodium dodecyl sulfate (SDS) (�90), Triton X-100 (90), Polyvinyl alcohol (95), Ethylene glycol (�99), and polyvinylpyrrolidone (PVP). DRS analysis indicated band gap for the Sm2(MoO4), Sm2(MoO4)3/GO, and Sm2(MoO4)3/C3N4 as 3.75, 3.15, and 3.4 respectively. The characteristics of the prepared nanostructures were studied through X-ray diffraction (XRD), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). Finally, the activity of the prepared Sm2(MoO4)3 as photo-catalysts for the degradation of different organic dyes such as methyl orange (MO), methylene blue (MB), and rhodamine B (Rh B) was evaluated. The photocatalytic property of Sm2(MoO4)3/C3N4 and Sm2(MoO4)3/GO for the degradation of MO, was obtained. Based on the empirical data Sm2(MoO4)3/C3N4 had the strongest photodegradation effect as compared to the other compounds tested after around 40 min. BET analysis revealed that the specific surface area of the Sm2(MoO4)3 nanocomposite prepared using C3N4 is 15 times that of in the absence of C3N4. Also, the cytotoxicity of synthesized samples was evaluated using MTT assay against human cell lines MCF-7 (cancer), and its IC50 was about 125 mg/L. © 202

Synergetic effect of graphene oxide and C3N4 as co-catalyst for enhanced photocatalytic performance of dyes on Yb2(MoO4)3/YbMoO4 nanocomposite

Here in, we report synthesis of novel hybrid photocatalyst by assembling graphene oxide (GO) and carbon nitride over Yb2(MoO4)3/YbMoO4 nanocomposite in order to investigate degradation of rhodamine B, methylene blue, and methyl orange. In addition, different capping agents (e.g. PEG, PVP, SDS, CTAB and Triton X-100) were utilized to investigate their impact on the morphology and particle size of the Yb2(MoO4)3/YbMoO4 nanocomposite. On the top of that, different parameters such as various mass ratio of precursors (GO, C3N4, Yb2(MoO4)3/YbMoO4), pH value, photocatalyst concentration were altered to investigate their impact on the degradation efficiency. Degradation results reveal that Yb2(MoO4)3/YbMoO4/GO and Yb2(MoO4)3/YbMoO4/C3N4 exhibits higher photocatalytic activity in comparison with pure Yb2(MoO4)3/YbMoO4. The crystalline phases, structure, morphology, and optical properties were characterized by a couple of techniques including X-ray diffraction, scanning electron microscopy, diffuse reflectance spectroscopy, and energy dispersive X-ray microanalysis. According to the BET results, Yb2(MoO4)3/YbMoO4/GO has specific surface area 1.5 times higher than pure Yb2(MoO4)3/YbMoO4. © 2019 Elsevier Ltd and Techna Group S.r.l
