“…Figure 3 depicts the FT-IR spectrum of D0, D10, D15, and D20 samples over the frequency range of 500-4000 cm −1 . The strong absorption band situated at IR band near 800 cm −1 is related to the MoO 4 2− cluster, which confirms that the SrMoO 4 and Dy-doping SrMoO 4 samples are formed under the synthetic conditions. In addition, the FT-IR spectra of these samples show a band at 1400-1600 cm −1 , which is assigned to the N-H bending and N-C stretching modes of -NH 2 groups in oleylamine and oleic acid.…”

“…The scheelite-structured molybdates in the AMoO 4 (A = Sr, Ba, Ca, Pb) family have been arousing great concern in recent years owing to their attractive properties and potential applications. [1][2][3][4][5][6] SrMoO 4 , as a representative scheelite-structured compound, has a tetragonal crystal symmetry with space group I41/a. Each Mo site is surrounded by four equivalent O sites in nearly tetrahedral configuration, and each Sr site is surrounded by eight O sites in nearly octahedral configuration.…”

“…And it shows excellent luminescence properties within the blue and green spectral regions, and can thus be used as a kind of self-activated luminescent materials. [7,8] Recent researches have shown that some molybdate compounds such as PbMoO 4 , NiMoO 4 , and BaMoO 4 exhibit photocatalytic properties of the degradation of organic pollutants. [9][10][11] Now, there are various modification approaches proposed including metal/nonmetal doping, heterojunction structure formation, and cocatatlysts loading in order to promote photocatalytic performance.…”

Dysprosium (Dy)‐doping SrMoO4 (with different molar ratio of Dy/Sr = 0/100, 10/100, 15/100 and 20/100) have been synthesized by high temperature thermal decomposition of metal–organic salt in organic solvent with a high boiling point. Their structures, morphology, and optical properties were characterized by X‐ray diffraction (XRD), high‐resolution tuning electron microscopy ((HR)TEM), X‐ray photo‐electron spectroscopy (XPS), and UV–vis diffuse reflectance spectroscopy (UV–vis DRS). Using this method, the pure phase, nano‐size, and low band gap of SrMoO4 sample are obtained. The results shows that the size of as‐synthesized SrMoO4 nanoparticles was about 200 nm. The band gap of Dy‐doped SrMoO4 ranges from 3.76–3.90 eV, and decreases with increasing Dy concentration. The photocatalytic performance of as‐syntheszied products were determined from the degradation of methylene blue (MB) by UV–vis light irradiation. The 15 mol%Dy‐doped SrMoO4 sample shows the best performance for photocatalytic degradation of methyl blue of nearly 100% in 120 min under visible irradiation, which is higher than most of those reported before. The present work is meaningful for revealing the underlying mechanism in photocatalyst and improving the photocatalytic performance.

Mn‐doped SrMoO4 nanocrystals were synthesized by thermal decomposition of metal–organic salt in an organic solvent with the doping content in the range 0–12 mol%. The structures, morphologies and optical properties were characterized using various techniques. The results suggest that Mo sites in the SrMoO4 lattice are substituted by the Mn dopant, the adsorption bands are found to be shifted toward the visible light region and the band gap becomes narrower correspondingly. The photocatalytic performance of the as‐synthesized product was determined using the degradation of methylene blue by visible light irradiation. The photocatalytic performance is enhanced with Mn doping, and the optimal degradation rate is 85% in 140 min for 5 mol% Mn doping. The enhanced photocatalytic activity with Mn doping may be ascribed to the energy band adjustment and effective photogenerated electron–hole separation caused by the Mn doping. A possible photocatalytic mechanism is also discussed.

Novel dahlia-like TiO 2 structures were successfully synthesized by an ethylenediamine (EDA)-assisted hydrothermal method. The EDA served as ligand and facilitated the growth of dahlia-like TiO 2 structures. Particularly, the dahlia-like TiO 2 structures were built by twodimensional (2D) thin nanosheets, which interconnected with each other. In addition, the dahlia-like TiO 2 structures own relatively large specific surface areas of 158.85 m 2 /g. Furthermore, the dahlia-like TiO 2 structures exhibit higher photocatalytic activity than that of commercial P25 for degradation of Rhodamine under UV light irradiation. The enhanced photocatalytic activity is due to the synergetic effect of the architecture and high BET surface area of the photocatalyst.
