“…The X value of AgVO3 is 5.86 eV. As indicated in Table (2), according to the calculation, the values of Eg of the valence band and the conduction band of silver vanadate nanorods are 2.35 eV and 0.53 eV, respectively, which is comparable to the values described in the literature [18]. Figure (3) shows the absorption analysis of pure chitosan and prepared thin films.…”

“…Some works have been demonstrated that narrows band gaps are related to better photocatalytic activity [52]. Since β-AgVO 3 is an efficient photocatalyst under visible light radiation [53], the samples produced by hydrothermal routes (H1 and H2) is expected to present better photocatalytic activity than the samples synthesized by precipitation (P1 and P2).…”

Silver vanadate, especially β-AgVO 3 , have a wide range of technological applications due to remarkable biological, optical, and electrical features. The structure, morphology, and properties of β-AgVO 3 are directly affected by synthesis conditions. A comparative study between two different synthesis routes (precipitation and hydrothermal) of β-AgVO 3 was systematically investigated in this work. X-ray diffraction, Raman spectroscopy, scanning electron microscopy, zeta potential, and UV-visible spectrometry results showed that the hydrothermal method produced more homogeneous samples of β-AgVO 3 , with elevated purity and crystallinity. In addition, the sample of β-AgVO 3 obtained by hydrothermal method had a wire-like morphology while that obtained by precipitation had irregular shape. Finally, the hydrothermal procedure showed more elevated reproducibility.

“…Over the past few decades, researchers have modified the AgVO 3 via preparation of heterojunction composite materials with other semiconductors which have suitable band potentials to reduce the recombination of charge carriers and hence, the photocatalytic activity has been improved. In addition, many AgVO 3 -based composite photocatalysts, such as AgCl/AgVO 3 [38], Ag 3 PO 4 /AgVO 3 [39], BiVO 4 /AgVO 3 [40,41], MoS 2 /AgVO 3 [42], graphene/AgVO 3 [43], g-C 3 N 4 /Ag/AgVO 3 [44,45], Ag 2 CrO 4 /AgVO 3 [46] and Ba 5 Ta 4 O 15 /AgVO 3 [47] have been reported to have the superior photocatalytic performance because of their increased electron-hole separation efficiency as compared with pure AgVO 3 .…”

A Facile Synthesis of Visible-Light Driven Rod-on-Rod like α-FeOOH/α-AgVO3 Nanocomposite as Greatly Enhanced Photocatalyst for Degradation of Rhodamine B

In this work, we have synthesized the rod-on-rod–like α-FeOOH/α-AgVO3 nanocomposite photocatalysts with the different amounts of solvothermally synthesized α-FeOOH nanorods via a simple co-precipitation method. The as-synthesized photocatalysts were characterized by X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, UV−Visible diffuse reflectance spectroscopy, scanning electron microscopy (SEM), element mapping, high-resolution transmission electron microscopy (HR-TEM) and X-ray photoelectron spectroscopy (XPS) analysis. The observed SEM images show that both α-AgVO3 and α-FeOOH exhibits the rod-shaped morphology with nano size. Furthermore, the photocatalytic activities of the obtained photocatalysts were evaluated towards the degradation of Rhodamine B (RhB) under visible-light irradiation. It is demonstrated that the 3 mg α-FeOOH added to the α-FeOOH/α-AgVO3 nanocomposite exhibited an enhanced photocatalytic performance as compared with the pure α-AgVO3 and α-FeOOH. This significant improvement can be attributed to the increased photo-excited electron-hole pair separation efficiency, large portion of visible-light absorption ability and the reduced recombination of the electron-hole pair. The recycling test revealed that the optimized nanocomposite exhibited good photostability and reusability properties. In addition, the believable photodegradation mechanism of RhB using α-FeOOH/α-AgVO3 nanocomposite is proposed. Hence, the developed α-FeOOH/α-AgVO3 nanocomposite is a promising material for the degradation of organic pollutants in an aqueous environment.
