Facile hydrothermal synthesis of vanadium oxides nanobelts by ethanol reduction of peroxovanadium complexes

“…and their derivatives have attracted increasing attention because they can be used as the electrode materials for electrochemical applications in recent years. As the intercalation compounds, V 3 O 7 Á H 2 O and VO 2 (B) are promising cathode materials in lithium-ion batteries [20,23,24,26,[55][56][57]. It was reported that the electrochemical properties of the electrode materials were influenced by many factors, such as intrinsic structure, morphology, and preparation methods.…”

“…Among them, vanadium oxide hydrate V 3 O 7 Á H 2 O has stimulated great interest because it can be used as the cathode materials in lithium-ion batteries [20,23,24]. Therefore, a variety of methods, such as template method [25], surfactant-assisted approach [ and hydrothermal/solvothermal synthesis [20,23,24,27,28], have been developed to prepare V 3 O 7 Á H 2 O nanostructures. However, most of these synthetic methods of fabricating V 3 O 7 Á H 2 O nanostructures are either based on templates, surfactants and using some reagents which are not environmentally friendly or through a complex and lengthy route.…”

Preparation of VO2(B) Nanoflake with Glycerol as Reductant Agent and its Catalytic Application in the Aerobic Oxidation of Benzene to Phenol

“…Recently nanostructured vanadium oxides have attracted great attention because of their size-dependent properties [1][2][3] and potential applications in catalysis [4], batteries [5][6][7], transistors [8,9], sensors [10][11][12] and nanodevices [13] (V 3? ).VO 2 has the property of being oxidized to V 2 O 5 (standard reduction potentials at 25°C: ?1.00 V) and being reduced to V 2 O 3 (standard reduction potentials at 25°C: ?0.36 V), and thus has the advantages of electrical and optical applications.…”

Simple Preparation of V2O5Nanostructures and Their Characterization

“…[6][7][8][9][10][11][12][13] In order to improve the performance of lithium batteries by employing vanadium pentoxide as a cathode material, a few methods have been used to prepare vanadium pentoxide with better characteristics, which includes the use of aerogels, xerogels, nanocomposites of LiV 2 O 5 with electronically conducting organic polymers and nanostructured materials. [9][10][11][12] There have been a few recent attempts to develop synthetic methods for nanomaterials of vanadium oxides but preparation of single-crystal vanadate nanostructures still remains challenging. Generally, nanomaterials are prepared in acidic media [2][3][4][5] but very few studies report their synthesis using basic media.…”
