Research on V2O5 nanostructures (nanofibers, nanoflowers, nanospheres) made by spray pyrolysis and solution-based routes, used for xylene gas sensing and, combined with graphene oxide, for glucose electrooxidation.
Hydrothermal, solution-combustion, and microwave heating each shape V2O5 into a distinct nanostructure, with the solution-combustion nanoflowers giving the most selective ethanol response.
A V2O5-graphene oxide hybrid made by electrochemical exfoliation offers a lower-cost, non-noble-metal alternative for direct glucose electrooxidation and sensing.
Higher precursor concentration turns spray-pyrolysis V2O5 into interconnected, flower-like nanofibers that give the strongest, most selective room-temperature xylene response among eight tested vapors.
