ABSTRACTWe have synthesized novel nickel and manganese vanadium oxides using the hydrothermal reactions of vanadium(V) pentoxide, Ni(CH3COO)2, and MnSO4 with an organic templating cation at 165°C. The [NH2(CH2)2NH2]2NiV6O14 has a monoclinic structure. It has some disordered V and 0 atoms in the V6014 layer, which appear to be very close to each other with occupation factor around 0.5. The disordered model was decomposed for two ordered configurations, which differ in the stacking of the layers. The (Mn+2)6(Mn+3)l−2/3z(OH)3(1−Z)(VO4)3[(VO4)l−2z(v207)z] (Z≈0. 1) phase has a hexagonal pipe morphology. These compounds were also characterized by electron microprobe, FTIR and TGA. They reacted readily with lithium, and their electrochemical behavior in lithium cells was determined.

ABSTRACTOur research on new cathode nano-materials for advanced lithium batteries has focused on the hydrothermal method for synthesis. We have synthesized two novel manganese vanadium oxides using the hydrothermal reactions of vanadium (V) pentoxide, [N(CH3)4]MnO4, and MnSO4 with an organic templating cation at 165°C. The 6-type [N(CH3)4]zMnyV2O5*nH2O has a monoclinic structure, a= 11.66(2)Å, b=3.610(9)Å, c= 13.91(4)Å, β= 108.8(2)°. It has a disordered V2O5 double layer and the Mn and N(CH3)4 ions reside between the layers. The γ-type MnV2O5 is orthorhombic, belongs to the space group Pnma, a=9.7585(2) Å, b=3.5825(l)Å, c= 11.2653(2) Å. These compounds were also characterized by electron microprobe, FTIR and TGA. They reacted readily with lithium, and their electrochemical behavior in lithium cells was determined.

Star-like CuO with submicrometer sizes was fabricated via a simple liquid-phase deposition with the assistant of PVP and Na2MoO4. The as-prepared CuO have been characterized by X-ray diffraction(XRD) and scanning electron microscopy (SEM). The results showed that the as-prepared CuO owned monoclinic structure, the concentrations of PVP, Na2MoO4 and NaOH are very important to the morphology of CuO. The quality of PVP impacts the formation of thin flakes on the skeletons. Meanwhile, the growth of dendritic skeletons was depended on the addition of Na2MoO4, and the effect of NaOH is to control the dimension of CuO structure.

<p>This review article mainly focused on the recent progress on the synthesis and characterization of emerging artificially engineered nanostructures of oxide materials as well as their potential applications. A fundamental understanding about the state-of-the-art of the synthesis for different size, shape and morphology, which can be tuned to the desired properties of oxide nanomaterials have discussed in details in this review. The present review covers the a wide range of artificially engineered oxide nanomaterials such as cadmium-, cupric-, nickel-, magnesium-, zinc-, titanium-, tin-, aluminium-, and vanadium-oxides and their useful applications in sensors, optical displays, nanofluids and defence.</p>

AbstractThe pH of the reaction media is a critical factor in the formation of new vanadium oxides with the tetramethylammonium (TMA) ion via the conventional hydrothermal method. New vanadium oxides; TMAV3O7, Li0.6V2−δO4−δ·H2O and Li0.6V2−δO4−δ, TMAV4O10, and two more new vanadium phases with d spacings of 11.5Å and 19.1Å are formed as the pH is varied with acetic acid. The synthesis and characterization of TMAV3O7, a new vanadium oxide with tetramethylammonium ions residing between its layers is discussed. The intercalation of alkylamines, DMSO, and water into Li0.6V2−δO4−δ·H2O is described. Microwave hydrothermal synthesis is a new and alternate soft chemistry technique used to accelerate the synthesis of TMAV4O10. This method also aided in the formation of a new cluster compound, [Li(H2O)4]2TMA(V10O28)·4H2O.
