Hydrothermal Synthesis of Nanostructured Vanadium Oxides
A wide range of vanadium oxides have been obtained via the hydrothermal treatment of aqueous V(V) solutions. They exhibit a large variety of nanostructures ranging from molecular clusters to 1D and 2D layered compounds. Nanotubes are obtained via a self-rolling process while amazing morphologies such as nano-spheres, nano-flowers and even nano-urchins are formed via the self-assembling of nano-...
متن کاملHydrothermal synthesis and crystal structures of two novel vanadium oxides containing interlamellar transition metal complexes
Two new vanadium oxide compounds, which contain interlamellar transition metal complexes bound to vanadium oxide sheets, were synthesized hydrothermally. The crystal structure of each reveals unusual coordination geometries and interlayer bonding. [Ni(2,29-bipyridine)]2[V12O32] (1) was prepared from the reaction of V2O5, NiO, H2O and 2,29-bipyridyl in the molar ratio 4:8:3312:0.5. The isomorpho...
متن کاملHYDROTHERMAL SYNTHESIS AND CHARACTERIZATION OF VANADIUM SILICATE MOLECULAR SIEVES WITH ANALCIME, MAGEDIITE AND ZSM-11 STRUCTURE
Vanadium silicates such as V-Al-analcime, V-analcime, V-magediite and V-ZSM-11 were synthesized using vanadium pentoxide or vanadyl sulfates. Vanadium silicates with analcime structure with and without aluminum (V-Al-analcime, V-analcime) were prepared as pure phase by hydrothermal crystallization from a gel with molar composition of (1 SiO2; 0.2 V2O5; 1 Na2O; 0.034 Al2O3; 35.7 H2O) and (1 SiO2...
متن کاملHydrothermal synthesis of vanadium nitride and modulation of its catalytic performance for oxygen reduction reaction.
A creative hydrothermal synthesis method followed by calcination for vanadium nitride (VN) is reported. The oxygen reduction reaction (ORR) study of the catalyst shows that VN possesses a comparable catalytic performance to commercial Pt/C catalyst. The ORR catalytic activity study of vanadium nitride, vanadium carbonitride, and vanadium carbide reveals that tuning anions offers a promising rou...
متن کاملNanostructured Metal Oxides Based Enzymatic Electrochemical Biosensors
Studies of nanobiosensors based on semiconductor nanostructured metal oxides are of practical and theoretical importance in biological science, environmental science and analytical chemistry (Wang et al., 2005; Luo et al., 2006; Valentini & Palleschi (2008); Chopra et al., 2007). These one-dimensional nanostructured metal oxides have profound applications in optics, optoelectronics, sensors, an...
