“…Tadjarodi et al prepared BiOCl nanoplates using bismuth nitrate pentahydrate and sodium chloride via ball milling (25). Guo et al reported the synthesis of BiOBr/(BiO) 2 CO 3 nanocomposites by a combination of solid state chemical reaction and water bath incubation (26). The solid solution BiOCl x I 1-x has been successfully prepared from Bi(NO 3 ) 3 Á5H 2 O by a solid state chemical process using polyethylene glycol 400 (PEG 400) as a morphology-controlled reagent (16).…”

CH COO(BiO) (denoted as BiOAc) is one of the most easily obtained bismuth compounds and was for the first time proposed by our group as an effective UV light photocatalyst. Herein, BiOCl Br (x refers to the feeding atomic ratio) were obtained using a facile solid state milling and subsequent water washing. More importantly, all of the as-prepared BiOCl Br possessed better visible light photocatalytic activity to the corresponding ones obtained by previously reported solution route. Especially at an optimal x value of 0.5, the solid solution showed the highest photodegradation efficiency (~100%) for rhodamine B (RhB) with a concentration of 30 mg L , whereas the degradation efficiency was only 63% over that obtained by solution route. Furthermore, the as-prepared BiOCl Br also exhibited excellent photodegradation activity for malachite green (MG). The superior photocatalytic performance of the as-prepared BiOCl Br could be attributed to its thinner sheetlike structures and highly exposed (001) facets, which enable effective separation of the photogenerated electrons and holes along the [001] direction. In addition, the as-prepared BiOCl Br revealed dramatic adsorption capacity for cationic dyes like MG, RhB and methylene violet (MV), as well as anion (Cr O ) owing to electrostatic interaction between cationic dyes and negatively charged surface of BiOCl Br , and positively charged surface in K Cr O solution (pH ≈ 3).

“…In recent years, bismuth subcarbonate (Bi 2 O 2 CO 3 ; BOC) as a member of Aurivillius‐related oxide family with layered structure has attracted much attention due to its unique photocatalytic activities . Many kinds of Bi 2 O 2 CO 3 ‐based hybrid composites such as Bi 2 O 2 CO 3 /β‐Bi 2 O 3 , Bi 2 O 2 CO 3 /MoS 2 , (BiO) 2 CO 3 /BiOX (X = Cl, Br and I), Bi 2 O 2 CO 3 /Bi 2 WO 6 , Bi 2 O 2 CO 3 /Bi 2 S 3 , Bi 2 O 2 CO 3 /CdS, Bi 2 O 2 CO 3 /BiPO 4 , g‐C 3 N 4 /Bi 2 O 2 CO 3 , Ag 2 O/Bi 2 O 2 CO 3 , Ag‐AgBr/Bi 2 O 2 CO 3 , Ag 3 PO 4 /Bi 2 O 2 CO 3 , Ag 2 CO 3 /Bi 2 O 2 CO 3 , and MWCNTs/Bi 2 O 2 CO 3 with enhanced photocatalytic activity and stability have been successfully synthesized. However, most of these BOC‐based composites are difficult to separate and recycle, seriously limiting their potential application.…”

Sheet-like Bi 2 O 2 CO 3 /ZnFe 2 O 4 magnetic nanocomposites (denoted as BOC-ZFO) with different amounts of magnetic ZnFe 2 O 4 (ZFO) nanoparticles were successfully produced by a simple hydrothermal route. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), energy dispersive X-ray spectroscopy (EDX), UV-vis diffuse reflectance spectroscopy (UV-vis DRS), vibrating sample magnetometer (VSM), and N 2 adsorption-desorption examination were utilized to analyze the structure, morphology, size, phase composition, optical and magnetic properties of the synthesized nanocomposites. The results demonstrated the successful deposition of uniform ZFO nanoparticles onto the surface of sheetlike BOC nanostructures. Then, the catalytic activity of magnetic BOC/ZFO nanocamposites was investigated for the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by using sodium borohydride (NaBH 4 ) in hydrous solution and at room temperature. The results showed that BOC/ZFO nanocamposite with 30%wt of ZFO showed the best performance in the reduction of 4-NP with 100% conversion into the amino derivative during 30 min. The effect of catalyst dosage was also investigated on the efficiency of reduction process. Under similar conditions, 2-nitrophenol (2-NP), 4-nitroaniline (4-NA) and 2-nitroaniline (2-NA) were also reduced to the amino derivatives within 16-29 min. The magnetic BOC/ZFO catalyst could be easily separated from the reaction system by an external magnet.
