“…Vanadium(V) oxide xerogels like crystalline V 2 O 5 are typical intercalation compounds with multiple valence state of vanadium which enables redox-dependent properties [4][5][6]. Due to the high intercalation capacity (for instance, a lithium intercalation capacity about 1.4 times larger than that of crystalline V 2 O 5 ) [7] they have a great potential for applications like reversible cathodes for lithium batteries [8,9], micro-batteries [6], supercapacitors [10], electrodes [11] and humidity sensors [12]. The reversible cation intercalation/deintercalation within the xerogel framework is concomitant with reversible reduction/oxidation of V(V) to V(IV) or to a lower valence vanadium state giving rise to easy color changes: yellow (V(V)), blue (V(IV)), green (V(III) or a mixture of V(V) and V(IV)) and violet (V(II)) [2,6].…”

V2O5 based materials are attractive cathode alternatives due to the many oxidation state switches of vanadium bringing about a high theoretical specific capacity. However, significant capacity losses are eminent for crystalline V2O5 phases related to the irreversible phase transformations and/or vanadium dissolution starting from the first discharge cycle. These problems can be circumvented if amorphous or glassy vanadium oxide phases are employed. Here, we demonstrate vanadate-borate glasses as high capacity cathode materials for rechargeable Li-ion batteries for the first time. The composite electrodes of V2O5 – LiBO2 glass with reduced graphite oxide (RGO) deliver specific energies around 1000 Wh/kg and retain high specific capacities in the range of ~ 300 mAh/g for the first 100 cycles. V2O5 – LiBO2 glasses are considered as promising cathode materials for rechargeable Li-ion batteries fabricated through rather simple and cost-efficient methods.

“…There are various synthesis methods that could be used to produce the V 2 O 5 nanostructures and thin films. For instances, Wei and Zhang synthesized V 2 O 5 nanotubes using hydrothermal method [22] and Yin et al grew porous V 2 O 5 micro/nanotubes by chemical vapor deposition [23]. In addition, Blanquart et al deposited V 2 O 5 thin films using atomic layer deposition [24] and Gotić et al synthesized V 2 O 5 powder by sol-gel method [25].…”

The visible-light-driven semiconductor photocatalysts are the current research focus techniques used to decompose organic pollutants/compounds. The photodegradation efficiency of organic compounds by photocatalyst is expected to be better compared to UV-light-driven semiconductor photocatalysts technique since the major components of our solar energy are visible light (∼44%). However, as most of the previous research work has been carried out using semiconductor photocatalysts in the form of powder, extra steps and costs are needed to remove this powder from the slurry to prevent secondary pollution. In this research work, we will explain our fabrication technique of V 2 O 5 nanoflakes by growing radially on PET fibers. By utilizing the flexibility and high surface area of polymeric fibers as novel substrate for the growth of V 2 O 5 nanoflakes, the Rhodamine B (RhB) could be degraded under visible light irradiation. The photodegradation of RhB solution by V 2 O 5 nanoflakes followed the 1st order kinetic with a constant rate of 0.0065 min −1 . The success of this research work indicates that V 2 O 5 nanoflakes grown on PET fibre could be possibly used as organic waste water purifier under continuous flow condition. A photodegradation mechanism of V 2 O 5 nanostructures to degrade RhB dye is proposed based on the energy diagram.
