a b s t r a c tIn this work, Bi 2 S 3 /SnS 2 heterojunction photocatalysts were prepared by combining a hydrothermal technique and a facile in situ growth method. The nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, inductively coupled plasma spectroscopy, X-ray photoelectron spectroscopy, UVeVis diffusion reflectance spectroscopy and roomtemperature photoluminescence spectra. Their photocatalytic performances were evaluated by degrading methyl orange (MO) in aqueous solution (50 mg/L) under visible light (l > 420 nm) irradiation. It was found that when the mass percentage of Bi 2 S 3 in Bi 2 S 3 /SnS 2 was 7.95 wt%, the as-prepared Bi 2 S 3 / SnS 2 nanocomposite showed the best photocatalytic activity for the degradation of MO. The highly improved performance of the Bi 2 S 3 /SnS 2 nanocomposite was mainly ascribed to the efficient charge separation.

“…Recently, bismuth‐based semiconductors, including BiOX (X = Cl, Br, and I), BiVO 4, Bi 2 WO 6 , and Bi 2 Sn 2 O 7, have attracted much attention due to their outstanding photo‐oxidation activity. Bi‐based semiconductors are believed to possess the hybridized energy band structures, which can effectively suppress the recombination of photogenerated electrons and holes .…”

BiOBr/Bi2Sn2O7 heterojunction photocatalysts were successfully synthesized by treating hydrothermal as‐prepared Bi2Sn2O7 nanoparticles with hydrobromic acid (HBr). Partial Bi2Sn2O7 nanoparticles reacted with HBr to form the sheet‐like BiOBr, and Bi2Sn2O7 nanoparticles distributed evenly on BiOBr sheets. BiOBr/Bi2Sn2O7 photocatalysts treated with different concentrations of HBr solution were successfully obtained, and their structures, morphologies, optical, and visible light photocatalytic properties were characterized by XRD, DRS, PL, SEM, and TEM. The experimental results showed that the BiOBr/Bi2Sn2O7 photocatalysts showed improved photocatalytic activity under visible light irradiation than pure Bi2Sn2O7. The sample treated with 0.08 mol/L HBr solution shows the best visible light photodegradation performance of rhodamine B. In addition, the active species and photocatalytic mechanism were discussed in detail.

The influence of ammonia on TiO 2 -MgFe 2 O 4 catalysts synthesized via a hydrolysis and co-precipitation, followed by calcination at 500 o C, was studied. Two different catalysts, TiO 2 -MgFe 2 O 4 (Am) and TiO 2 -MgFe 2 O 4 (W), were prepared using Ti-precursors, which were synthesized by the hydrolysis of Ti-butoxide with and without ammonia. The resulting TiO 2 -MgFe 2 O 4 catalysts were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), specific surface area measurements, X-ray diffraction, and UV-vis diffuse reflectance techniques. It was revealed that strong electronic coupling exists between the TiO 2 and MgFe 2 O 4 components within the TiO 2 -MgFe 2 O 4 catalysts. Photocatalytic activity toward Rhodamine B (RhB) was investigated in aqueous solution under visible light irradiation. TiO 2 -MgFe 2 O 4 (W) was found to be an effective catalyst and had several advantages over TiO 2 -MgFe 2 O 4 (Am). These results clearly highlight that ammonia had a significant influence on the photocatalytic activity of the TiO 2 -MgFe 2 O 4 catalysts. Therefore, the results reported herein indicate that TiO 2 -MgFe 2 O 4 is a green, low-cost, and highly efficient photocatalyst for environmental remediation.
