Enhanced 1-butylamine gas sensing characteristics of flower-like V2O5 hierarchical architectures

Vanadium oxide hierarchical architectures have been successfully synthesized using a facile hydro thermal method. The as-prepared V2O5 hierarchical architectures are assembled by nanobelts and present a unique radial flower-like morphology. The as-prepared V2O5 hierarchical structures are used for organic polluted and toxic gas 1-butylamine gas detection. The gas sensors based on V2O5 hierarchical architectures present excellent 1-butylamine gas sensing performances. Such as a fast response time (9 s), high sensitivity, good selectivity and superior repeatability, all these properties are predominantly attributed to the unique nanobelt-assembled radial flower-like structure and ammonium ions intercalation. The obtained V2O5 hierarchical architectures will hold promising potential in the fabrication of efficient and effective 1-butylamine gas sensors for practical applications. (C) 2017 Elsevier B.V.
