Abstract
The chemical and physical synthetic strategies for the preparation of nanomaterials are time-consuming, costly and toxic. To address these issues, Phyto-assisted synthesis of nanomaterials can be considered as a promising strategy. Herein, V 2 O 5 nanomaterial has been synthesized by using Azadirachta indica (Neem) leaf extract. The V 2 O 5 nanomaterial was characterized by employing multiple techniques, such as UV-Vis, FTIR, XRD, FE-SEM and EDX. The results showed that V 2 O 5 nanomaterial possesses nanoplate’s type morphology with 30–50[Formula: see text]nm diameters. Further, cyclic voltammetric studies showed the good durability during the voltammetric scans in 2M KCl electrolyte at 50[Formula: see text]mV/s scan rate and the V 2 O 5 nanoplates may be served as a promising cathodic candidate in Li-ion secondary batteries. Moreover, the antimicrobial activity of the prepared V 2 O 5 nanoplates was evaluated against the bacteria viz. S. typhi, S. aureus, B. subtilis, E. coli and fungi; F. species, A. flavus, P. triticina and A. niger by using the serial dilution method. The results suggested that V 2 O 5 nanoplates possess comparable antimicrobial activity comparable to standard drug Streptomycin against the used pathogens.
