“…The logarithm of the current density [ln( J )] was also plotted against the square root of the electric field [ E 1/2 ] in Figure . It can be determined that the straight-line nature observed at a medium electric field between 240 and 360 V/cm implied the Schottky mechanism, , as shown in Figure a, while at high electrical fields, the observed straight line in Figure b was related to the Poole-Frenkel mechanism. , It is anticipated that the novel silver trimolybdate single-crystalline NWs may have unique applications in microelectrodes or microsensors, which is similar to the novel vanadate materials. − …”

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.

“…The dimensions of these hexagons network of hydrogen bonds [17]. The characteristic band for crystal water around 1620 cm -1 [15] is absent, which provides evidence for the pristine material being water-free NH 4 V 3 O 8 . This could not be achieved by using the conventional hydrothermal route [17].…”

“…The traditional method is to use raw NH 4 VO 3 as vanadium source, and a mineral acid (HCl or H 2 SO 4 ) to adjust the initial pH value and to accomplish an -4 -acid hydrolysis [15,16]. Hydrothermal synthesis is a more efficient method to produce NH 4 V 3 O 8 [17].…”

Water-free NH 4 V 3 O 8 microcrystals have been successfully synthesized by a microwave-assisted hydrothermal method. The products were characterized by means of X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, thermal gravimetric analysis, cyclic voltammetry, and galvanostatic cycling. The results show phase-pure products whose particle size and morphology can be tailored by varying the reaction conditions, i.e., reaction temperature, synthesis duration, and initial pH value. For instance, at low pH (2.5 -

“…One-dimensional (1D) inorganic nanomaterials with various shapes and morphologies, such as nanotubes, nanowires, nanorods and nanobelts generally show enhanced physiochemical applications in various areas due to their high surface to size effects and reduced dimensionality not only have been attracting a great deal of research interest in recent years, but also they have been emerging as one of the most powerful and diverse classes of functional nanomaterials that are having a key impact on science and technology (Huang et al, 2001;Song et al, 2005;Comini et al, 2005;Mai et al, 2006;Fang et al, 2011a,b;Li et al, 2012;Peng et al, 2014). In particular, as one of the most important 1D-material structures quasione-dimensional nanobelts appear to have unique ability to combine a number of essential diagnostic, imaging, delivery and dosage properties and thus can be functionalized accordingly (Pan et al, 2001;Mo et al, 2002;Wang, 2004;Yu et al, 2008;Ahmad et al, 2011).…”

Hausmannite Mn 3 O 4 nanobelts were synthesized from manganese acetate and potassium hydroxide precursors in the presence of melamine-ethanol-distill water via the reflux and solvothermal methods. X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopes confirm the composition of the as-prepared product. Field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), selected area electron diffraction (SA-ED), high resolution transmission electron microscopy (HR-TEM) and N 2 adsorption-desorption isotherm results showed that the as-fabricated sample exhibits a nanosized belt-like crystal, single crystalline, tetragonal phase structure and high BET surface area. The effects of the reaction conditions such as melamine amount, solvent ratios and reaction time on the morphology of the products were studied. The band gap of the as-synthesized products was calculated via diffuse reflectance spectral analysis and their activity of catalytic oxidation was evaluated by degradation of diphenylthiocarbazone under visible-light irradiation. GC-MS instrument was used to monitor the temporal course of the catalytic reaction. The results showed that the degradation efficiency of diphenylthiocarbazone catalyzed by Mn 3 O 4 nanobelts was higher than that which had been prepared in particle and sheet-like nanocrystals.
