“…Polymer electrolytes based on chitosan doped with AgNO 3 is reported to be thermally stable where it did not show any drop in conductivity at the temperature range of 278 to 312 K [11]. Polymer electrolyte doped with silver salt has been applied in a battery [12]. The present work studied the conductivity and dielectric properties of corn starch doped with AgNO 3 polymer electrolyte films at temperature range of 298-358 K. Experimental 2 g of corn starch powder (Unilever) was dissolved in 50 ml distilled water.…”

Ionic conductivity and dielectric properties of starch based polymer electrolytes doped with silver nitrate (AgNO 3 ) at elevated temperatures were studied. The solid polymer electrolytes were prepared using the solution cast method. X-ray diffraction (XRD) analysis implied that the incorporation of 6 wt.% AgNO 3 increased the amorphous phase of the electrolyte. Temperature dependence conductivity plots showed that electrolyte containing 6 wt.% AgNO 3 obeyed Arrhenius rule with activation energy, E a of 0.71 eV. The effect of temperature on the dielectric properties of the electrolyte was also studied in relation to the conductivity properties. The variation of dielectric loss with frequency was obtained from the power law exponent. Temperature dependence of the power law exponent concluded that the conduction mechanism of the 94 wt.% starch-6 wt.% AgNO 3 electrolyte followed the correlated barrier hopping (CBH) model.

“…Silver molybdates, as one kind of metal molybdates, such as Ag 6 Mo 10 O 33 , Ag 2 Mo 2 O 7 , and Ag 2 Mo 4 O 13 nanowires (NWs), wire-like Ag 2 MoO 4 , and Ag 2 Mo 3 O 10 ·1.8H 2 O, have attracted much attention, due to their important application in conducting glass − and ammonia sensing material. , During the past decades, methods of preparing silver molybdates have been proposed, but most of them are traditionally synthesized by straight and harsh reaction in the MoO 3 /Ag 2 O system. , Recently, solution synthesis of low-dimensional silver molybdate nanostructures has been reported. ,, For example, Cui et al have prepared ultralong Ag 6 Mo 10 O 33 NWs . Nagaraju et al reported the synthesis of silver molybdate nanorods/nanowires/multipods .…”

Ultralong Silver Trimolybdate Nanowires: Synthesis, Phase Transformation, Stability, and Their Photocatalytic, Optical, and Electrical Properties

Ultralong orthorhombic silver trimolybdate nanowires (NWs) can be synthesized by a simple hydrothermal process without using any structure directing agent. Their phase transformation and stability to thermal and modeling sunlight from a Xe lamp have been systematically studied. Well-dispersed Ag nanoparticles can in situ form on the backbone of the nanowires by photoirradiation, and their photocatalytic and optical properties have been investigated. The investigations on photocatalytic, photoluminescent, and surface-enhanced Raman scattering (SERS) of the as-synthesized nanowires indicate that these nanowires loaded with Ag nanoparticles by photoirradiation can be a new kind of photocatalytic and luminescent material and potentially can be used as an efficient SERS substrate. The electrical conductivity of an individual nanowire exhibits almost nonlinear and symmetric current/voltage (I/V) characteristics for bias voltages in the range of -5 to 5 V. Ohmic mechanism, Schottky, and the Poole-Frenkel emission play an important part, respectively, in low, medium, and high electrical fields.

“…Silver molybdates have attracted much attention as an important family of conducting glass and ammonia sensing materials due to easy manipulation of their morphologies by solution synthesis. − More recently, one-dimensional, quasi-microstructured Ag 2 Mo 3 O 10 wires (Ws) have been developed as a plasmonic photocatalyst for degradation of Rh.B and have mechanisms similar to those of previous silver salt (halide or phosphate) photocatalysts . These plasmonic silver salt photocatalysts can significantly absorb visible light due to their localized surface plasmon resonance when photoinduced electrons reduce Ag ions to metallic Ag 0 particles on the surface of the photocatalyst .…”

We report a simple and versatile strategy for hybridizing 1-D silver trimolybdate wires (Ag2Mo3O10 Ws) and graphene oxide (GO) by a direct solution process. Because of the photoactive nature of Ag2Mo3O10 Ws, Ag particles were uniformly formed on their surfaces with the assistance of solar light. Enriched surface functional groups of GO from chemical activation induce a chemical coordination with these Ag particles. As a result, a uniform ternary hybrid mixture was successfully formed with metallic Ag nanoparticles as a bridge connecting activated GO and Ag2Mo3O10 Ws. We found that both excited GO and Ag2Mo3O10 could generate electron/hole pairs separated in space by metallic Ag as a solid-state electron mediator. The novel photocatalytic mechanism was confirmed using photocurrents, the electronic-band structure, and photoactivity correlation analysis.
