“…The diffraction peaks labeled as black can be indexed to the pure phase of β-AgVO 3 with the monoclinic structure (JCPDS 01-086-1154). However, the peak intensities are different from the standard card and another reference [29]. That is, the peak for the (601) plane in this pattern is much stronger, while that for the (203) plane is much weaker.…”

This study reports a visible light-driven plasmonic photocatalyst of Au deposited AgVO nanocomposites prepared by a hydrothermal method, and further in situ modification of Au nanoparticles by a reducing agent of NaHSO in an aqueous solution at room temperature. Various characterization techniques, such as SEM, TEM, XRD, EDS, XPS, and Brunauer-Emmett-Teller, were used to reveal the morphology, composition, and related properties. The results show that belt-like AgVO nanoparticles with a width of ∼100 nm were successfully synthesized, and Au nanoparticles with controlled sizes (5-20 nm) were well distributed on the surface of the nanobelts. The UV-vis absorption spectra indicate that the decoration of Au nanoparticles can modulate the optical properties of the nanocomposites, namely, red shift occurs with the increase of Au content. The photocatalytic activities were measured by monitoring the degradation of Rhodamine B (RhB) with the presence of photocatalysts under visible light irradiation. The photodegradation results show that AgVO nanobelts exhibit good visible light photocatalytic activities with a degradation efficiency of 98% in 50 min and a reaction rate constant of 0.025 min towards 30 ppm RhB. With the modification of Au nanoparticles, photocatalytic activity basically increases with the molar ratio of Au to V. Among the Au@AgVO nanocomposites, the 3% (molar ratio) Au decorated AgVO nanobelts showed the highest photocatalytic activity, and the k (0.064 min) was almost two times higher than that of the pure AgVO nanobelts. This can be attributed to several factors including specific surface areas, optical properties, and the energy band structure of the composites under visible light illumination. These findings may be useful for the practical use of visible light-driven photocatalysts with enhanced photocatalytic efficiencies for environmental remediation.

“…The environmental monitoring of amine vapors are of particular interest since both aliphatic and aromatic amines can induce toxicological effects to humans even at minimal concenTo date, diverse nanostructures based on transition metal vanadates have been reported, including ␤-AgVO 3 [12,13], ␣-CuV 2 O 6 [14],CuV 3 O 8 [15], Co 2 V 2 O 7 [16], ZnV 3 O 8 [17], Na 1.08 V 3 O 8 [18], MnV 2 O 6 [19], BiVO 4 [20], InVO 4 [21] and FeV 3 O 8 [22]. Among them, iron vanadate (FeVO 4 ), an n-type semiconductor (E g = 2.0 eV) with a triclinic structure [23], has been widely studied in terms of its morphological control and applications, including nanoplatelets for gas-sensors [22][23][24], nanosheets for photocatalysis [25], and nanorods for lithium-ion batteries [24,26].…”

“…Recently, Silver vanadium oxides, such as AgVO 3 and Ag 0.35 V 2 O 5 , have attracted increasing attention for their application in batteries because of their unique electronic structure24. In particular, it has been reported that the electrical conductivity of Ag 0.35 V 2 O 5 nanowires is 0.5 S/cm, about 6–7 times higher than that of V 2 O 5 nanowires25, and the amine sensitivity of Ag 0.35 V 2 O 5 is much higher compared with V 2 O 5 particles26.…”

Much greater surface-to-volume ratio of hierarchical nanostructures renders them attract considerable interest as prototypical gas sensors. In this work, a novel resistive gas sensor based on TiO2/Ag0.35V2O5 branched nanoheterostructures is fabricated by a facile one-step synthetic process and the ethanol sensing performance of this device is characterized systematically, which shows faster response/recovery behavior, better selectivity, and higher sensitivity of about 9 times as compared to the pure TiO2 nanofibers. The enhanced sensitivity of the TiO2/Ag0.35V2O5 branched nanoheterostructures should be attributed to the extraordinary branched hierarchical structures and TiO2/Ag0.35V2O5 heterojunctions, which can eventually result in an obvious change of resistance upon ethanol exposure. This study not only indicates the gas sensing mechanism for performance enhancement of branched nanoheterostructures, but also proposes a rational approach to design nanostructure based chemical sensors with desirable performance.
