“…39-0256). 23,24 The characteristic peaks at 31.82, 33.66, 34.74, and 36.81°correspond to the (120), (121), (112), and (022) lattice planes of Ag 2 S (JCPDS No. 14-0072), which indicate the prepared monoclinic structure of Ag 2 S. 25 Furthermore, the diffraction peak of the Ag 2 S−Bi 2 WO 6 composite does not shift significantly after loading Ag 2 S, indicating that loading of Ag 2 S particles does not change the lattice structure of Bi 2 WO 6 but is located on its surface.…”

A three-dimensional flower-shaped Bi2WO6 has been prepared by a hydrothermal procedure without the addition of an auxiliary agent and under neutral conditions with ultrapure water serving as solvent, and the Ag2S–Bi2WO6 composite with weight ratios of 5, 10, and 15% was prepared by a hydrothermal method. The crystallinity, morphology, mode of binding, and optical properties of the Ag2S–Bi2WO6 composite were characterized, the results of which showed that the composite had excellent dispersion, crystallinity, and purity. The composite with a weight ratio of 10% had the best photocatalytic performance, and the degradation rate of tetracycline reached 95.51% within 120 min, an increase of 27.35% over Bi2WO6. In experiments, some focus was given to the effect of the initial solution pH and the concentrations of humic acid and inorganic anions on the degradation efficiency. Based on free radical capture experiments and the semiconductor theory, the main active substances and mechanisms in the optical catalytic reaction process were studied, and speculation was given concerning the degradation pathway for the target pollutants. This study has conceived novel methods for the development of dual semiconductor systems consisting of a Ag NP composite and in doing so has provided new approaches for the development and photocatalysis for water pollution control.

“…Indeed, when the XRD pattern is locally enlarged between 30°and 40° ( Figure S2 ), the peaks of the fluorine-doping sample shift slightly to a larger 2θ value, reflecting the shrinkage of the crystal lattice. The shrinkage of the lattice may be caused by the substitution of the O 2− lattice by F − which proves fluorine doping [ 24 ]. Specifically, the peak intensity of FNCH is generally stronger than that of NCH, indicating the higher mass loading of the doped sample.…”

Cathode materials have impeded the development of aqueous Zn batteries (AZBs) for a long time due to their low capacity and poor cycling stability. Here, a “two birds with one stone” strategy is devised to optimize the Ni–Co hydroxide cathode material (NCH) for AZBs, which plays an essential role in both composition adjustment and morphology majorization. The F-doped Ni–Co hydroxide (FNCH) exhibits a unique nanoarray structure consisting of the 2D flake-like unit, furnishing abundant active sites for the redox reaction. A series of analyses prove that FNCH delivers improved electrical conductivity and enhanced electrochemical activity. Contributing to the unique morphology and adjusted characteristics, FNCH presents a higher discharge-specific capacity, more advantageous rate capability and competitive cycling stability than NCH. As a result, an aqueous Zn battery assembled with a FNCH cathode and Zn anode exhibits a high capacity of 0.23 mAh cm−2 at 1 mA cm−2, and retains 0.10 mAh cm−2 at 10 mA cm−2. More importantly, the FNCH–Zn battery demonstrates no capacity decay after 3000 cycles with a conspicuous capacity of 0.15 mAh cm−2 at 8 mA cm−2, indicating a superior cycling performance. This work provides a facile approach to develop high-performance cathodes for aqueous Zn batteries.

“…SCFs can promote the formation of superoxide free radical, which is the main active substance in degrading RhB. Chen et al 222 synthesized F-doped Bi 2 WO 6 composite materials through a simple one-step hydrothermal method, and combined with X-ray diffraction, X-ray photoelectron spectroscopy and energy spectrum analysis, proved that F had been successfully doped into the lattice of Bi 2 WO 6 . With the doping of F, the morphology of Bi 2 WO 6 changes from two-dimensional ultra-thin nanosheet to hierarchical nanoflower microstructure.…”
