“…Hence, preparation of AgI/ZnO nanocomposites with one-pot methodology will be highly valuable in the field of photocatalytic processes [22]. In recent years, preparation of different nanomaterials using microwave irradiation method has attracted extensive attention, owing to its advantages of short reaction time, small particle size, narrow particle size distribution, and high purity [23][24][25][26][27]. Under microwave irradiation, the electromagnetic waves interact with dipole moments of the molecules, leading to dielectric heating of the reaction system [28].…”

A B S T R A C TIn the present work, a microwave-assisted one-pot method was applied for preparation of the ZnO/AgI nanocomposites. One-pot, large-scale, and short preparation time are main advantages of this method. Photocatalytic activity of the nanocomposites in degradation of rhodamine B under visible-light irradiation is remarkably depended on mole fraction of AgI and the superior activity was seen for the nanocomposite with 0.342 mol fraction of silver iodide. The degradation rate constant over this nanocomposite is about 10-fold higher than that of the ZnO nanostructures. Photoluminescence spectra confirmed that separation of the charge carriers in the nanocomposites is more intensive than the ZnO nanostructures. Furthermore, it was observed that the microwave irradiation time, calcination temperature, and scavengers of the reactive species have considerable influence on the degradation reaction. More importantly, the photocatalyst retains about 80% of its activity after using for five cycles.

“…Over the last few years, bismuthyl ion (BiO + ) based nanostructures have been studied to develop new adsorbent–photocatalytic systems owing to their peculiar physicochemical properties, layered structures, morphologies, and low toxicity. − In particular, bismuth oxyhalogenides (BiOX, X = Cl, Br, I, and their mixtures) and bismuth subcarbonate, (BiO) 2 CO 3 , nanostructures displayed encouraging performances. Besides BiOCl, further bismuth oxychlorides with different stoichiometry, such as Bi 24 O 31 Cl 10 , Bi 3 O 4 Cl, Bi 12 O 17 Cl 2 , etc., are possible .…”

Bi12O17Cl2/(BiO)2CO3 nanocomposite materials were studied as bifunctional systems for depuration of wastewater. They are able to efficiently adsorb and decompose rhodamine B (RhB) and methyl orange (MO), used as model pollutants. Bi12O17Cl2/(BiO)2CO3 nanocomposites were synthesized at room temperature and ambient pressure by means of controlled hydrolysis of BiCl3 in the presence of a surfactant (Brij 76). Cold treatments of the pristine samples with UV light or thermal annealing at different temperatures (370–500 °C) and atmospheres (air, Ar/30% O2) were adopted to modulate the relative amounts of Bi12O17Cl2/(BiO)2CO3 and hence the morphology, surface area, ζ-potential, optical absorption in the visible range, and the adsorption/degradation of pollutants. The best performance was achieved by (BiO)2CO3-rich samples, which adsorbed 80% of MO and decomposed the remaining 20% by visible light photocatalysis. Irrespective of the dye, all of the samples were able to almost complete the adsorption step within 10 min contact time. Bi12O17Cl2-rich composite materials displayed a lower adsorption ability, but thanks to the stronger absorption in the visible range they behaved as more effective photocatalysts. The obtained results evidenced the ability of the employed strategy to modulate sample properties in a wide range, thus pointing out the effectiveness of this approach for the synthesis of multifunctional inorganic materials for environmental remediation

“…Semiconductor-based photocatalysts are taken as cost-effective, environmentally friendly, and sustainable materials to remove a series of environmental pollutants because of its promising applications in energy generation and environmental purification (He et al, 2015;Huang et al, 2015). As various kinds of highly efficient photocatalysts capable of exploiting the solar spectrum have been developed, the bismuth oxyhalides (BiOX, X ¼ Cl, Br, I) family is one of them being extensively studied currently (Dash et al, 2014;Guo et al, 2014), due to their superior photocatalytic activities.…”

In this study, a novel composite containing an iron based metal-organic framework (MOF) and BiOBr was successfully synthesized by a simple method, and was fully characterized by X-ray diffraction patterns, Fourier transform infrared spectra, UV-vis diffuse reflectance spectra, and transmission electron microscopy. Moreover, the photocatalytic activities of BiOBr/MIL-88B(Fe) composites and the pure materials were evaluated by measuring the degradation of Rhodamine B under visible light. The results show that the composite exhibits better photocatalytic activities than pure materials, which can be ascribed to the high adsorption capacity of MIL-88B(Fe) and the enhanced separation of photogenerated charge carriers from assembly of MIL-88B(Fe) on BiOBr. And the effects of various operating parameters such as catalyst dosage, medium pH, the mass ratio of BiOBr, and MIL-88B(Fe) and the dye initial concentration on the degradation of RhB have been studied.
