(figure presented) Burning an ethanolic solution of vanadyl(IV) acetylacetonate in a glass beaker affords monoclinic VO2 [VO 2(M)], and thus brings this formerly expensive oxide into the realm of conventional laboratory synthesis. Differential scanning calorimetry (DSC) showed consistent heating and cooling curves (see picture) for 50 reversible transitions between VO2(M) and the higher-temperature rutile phase of VO2.

Various types of sulfides are selectively oxidized to sulfoxides in good to excellent yields in aqueous media using 30% aqueous hydrogen peroxide as an oxidant in the presence of catalytic amounts of a VO(acac)2-exchanged strongly acidic polymeric resin catalyst in water at room temperature. The catalyst can be recovered and reused at least five times without loss of activity and selectivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C10H14O5V, you can also check out more blogs about3153-26-2

Non-aqueous electrolytes are stable over wide electrochemical potential windows, generally <2 V, and therefore hold promise for enabling higher energy and power density redox flow batteries (RFBs). Nevertheless, the development of non-aqueous RFBs is at an early stage and significant research efforts are needed to demonstrate non-aqueous RFBs with performance characteristics that exceed those of aqueous RFBs. The membrane or separator is a critical component that to a great extent determines the performance of RFB systems for practical applications. In this work, the performance of a RFB was evaluated with Nafion 1035 membranes and Daramic 175 SLImicroporous separators. The non-aqueous electrolyte was based on vanadium (III) acetylacetonate. This chemistry possesses two couples over ?2.2 V. Charge-discharge cycles were performed in a RFB at a current density of 10 mA cm-2. Coulombic and energy efficiencies of 91% and 80% were achieved using the Nafion membrane. A similar RFB using the Daramic microporous separator achieved columbic and energy efficiencies of 73% and 68%, respectively. The source of capacity decay during multiple charge-discharge cycles was also investigated. The loss in the capacity was related to the poor chemical stability of the vanadium acetylacetonate in the positive electrolyte during battery cycling. Because enzymes can increase reaction rates by enormous factors and tend to be very specific, COA of Formula: C10H14O5V, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 3153-26-2

A (1+1) macrocyclic calix[4]arene based Schiff base derivative has been synthesized and was subjected to complexation with different ions or ionic species, viz., VO2+, UO22 +, Fe3+, Ni2+, Cu2+ and Zn2+. Both the conjugate and the complexes were characterized using various spectral techniques, viz.; FTIR, 1H, 13C NMR and FAB mass. The complexes have been further characterized by UV-Vis, EPR and magnetic susceptibility, while the iron complex was studied further by Moessbauer spectroscopy. On the basis of all these studies, the VO2+ and UO22 + complexes were found to be mononuclear, whereas all the other complexes were found to be dinuclear. Based on the studies, the iron complex was found have a distorted octahedral high spin Fe(III) center with an antiferromagnetically coupled dinuclear core in the complex.

Two series of Cu2+ and V4+ doped anatase TiO2 samples were prepared using the microemulsion synthetic route by varying the metal/Ti ratio. The samples were characterized by UV-vis absorption, nitrogen physisorption, XRD, XPS, Raman and EPR spectroscopy. Their photocatalytic activity against toluene photo-oxidation was evaluated under both sunlight-type and pure UV light irradiation. The photoactivity was drastically affected by the dopant content. Low or moderate metal doping levels were beneficial for toluene photo-degradation, while high doping levels suppressed the photoactivity. Electron paramagnetic resonance (EPR) spectroscopy was employed to study the structure and electronic characteristics of the prepared catalysts and elucidate the physicochemical aspects governing the photoactivity. The presence of different Cu and V species was detected as a function of the metal content in the catalyst. EPR spectroscopy revealed that photoinitiated charge formation takes place in both the Cu and V doped TiO2 series and that charge separation may be enhanced depending on the dopant content. A direct correlation between the dopant species formed and hole formation was observed in both series. Photoactivity is directly correlated with the formation of holes, which in turn is tuned by the dopant content regulating the isolated metal centers versus metal cluster formation. Low or moderate doping levels enhanced the separation of photo-produced electron-hole pairs via accepting e-, eliminating trapping sites related to localized Ti3+ states and increasing the abundance of hole species. At higher levels where metal clusters prevailed, dopants acted as recombination centers, deteriorating the photoactivity in both TiO2-doped series. The results indicate a general mechanism potentially applicable to similar photocatalytic systems.

Two new dinuclear oxidovanadium(V) complexes, [V2O2(L1)(OCH3)2(CH3OH)2]·2(CH3OH) (1) and [V2O2(L2)(OCH3)2(CH3OH)2]·2(CH3OH) (2), were synthesized from the reaction of VO(acac)2 and hexa-dentate N2O4-donor hydrazone ligands (H4L1 and H4L2) in methanol solvent. The ligands and complexes were characterized by elemental analysis and spectroscopic methods. Single crystal X-ray analysis of the brown crystals of complexes 1 and 2 indicated that these complexes are dinuclear oxidovanadium(V) complexes which the metal ions have distorted octahedral geometry. There are several strong and directed hydrogen bonding interactions in the crystal packing of 1 and 2 which stabilize their crystalline format. The catalytic activity of these complexes was tested in the oxidation of thioanisole using H2O2. These studies indicated both complexes have high catalytic activity in the oxidation of thioanisole. The complexes were further studied by DFT and TDDFT theoretical calculations.

A series of mononuclear non-oxido vanadium(IV) [VIV(L1-4)2] (1-4), oxidoethoxido vanadium(V) [VVO(L1-4)(OEt)] (5-8), and dinuclear mu-oxidodioxidodivanadium(V) [VV2O3(L1)2] (9) complexes with tridentate aroylazine ligands are reported [H2L1 = 2-furoylazine of 2-hydroxy-1-acetonaphthone, H2L2 = 2-thiophenoylazine of 2-hydroxy-1-acetonaphthone, H2L3 = 1-naphthoylazine of 2-hydroxy-1-acetonaphthone, H2L4 = 3-hydroxy-2-naphthoylazine of 2-hydroxy-1-acetonaphthone]. The complexes are characterized by elemental analysis, by various spectroscopic techniques, and by single-crystal X-ray diffraction (for 2, 3, 5, 6, 8, and 9). The non-oxido VIV complexes (1-4) are quite stable in open air as well as in solution, and DFT calculations allow predicting EPR and UV-vis spectra and the electronic structure. The solution behavior of the [VVO(L1-4)(OEt)] compounds (5-8) is studied confirming the formation of at least two different types of VV species in solution, monomeric corresponding to 5-8, and mu-oxidodioxidodivanadium [VV2O3(L1-4)2] compounds. The mu-oxidodioxidodivanadium compound [VV2O3(L1)2] (9), generated from the corresponding mononuclear complex [VVO(L1)(OEt)] (5), is characterized in solution and in the solid state. The single-crystal X-ray diffraction analyses of the non-oxido vanadium(IV) compounds (2 and 3) show a N2O4 binding set and a trigonal prismatic geometry, and those of the VVO complexes 5, 6, and 8 and the mu-oxidodioxidodivanadium(V) (9) reveal that the metal center is in a distorted square pyramidal geometry with O4N binding sets. For the mu-oxidodioxidodivanadium species in equilibrium with 5-8 in CH2Cl2, no mixed-valence complexes are detected by chronocoulometric and EPR studies. However, upon progressive transfer of two electrons, two distinct monomeric VIVO species are detected and characterized by EPR spectroscopy and DFT calculations.
