Preparation and Characterization of PEG Surfactant V2O5 Nanotubes as Cathode Materials

Disodium citrate-assisted hydrothermal synthesis of V2O5 nanowires for high performance supercapacitors

“…14 In order to overcome the above shortcomings, effective methods have been devoted to synthesize nanostructured V 2 O 5 , which is benecial to shorten diffusion path for ions, enhance contact area between electrode and electrolyte, and improve capacitive property. [14][15][16] Recently, many researchers have studied to synthesize diverse structures of V 2 O 5 nanomaterials, such as nanowires, 14,[17][18][19][20][21] nanoblets, 22 nanotubes, 23 nanoowers, 20 nanoballs [24][25][26] and so on. Various synthetic methods including solgel route, 25 ame spray method, 27 hydrothermal and solvothermal method for different structures of V 2 O 5 have been reported.…”

“…As is known, the way to overcome these limitations by additive agent has drawn great interest of researchers. [22][23][24] However, there are few reports on preparation of V 2 O 5 nanomaterials using disodium citrate as additive agent. Saravanakumar et al 28 constructed V 2 O 5 nanoporous network via simple capping agent-assisted precipitation technique with disodium citrate as capping agent, showing the specic capacitance of 316 F g À1 with 0.5 M K 2 SO 4 electrolyte.…”
