摘要：

Herein, we report a simplistic approach to prepare vanadium pentoxide nanofibers (V2O5 NFs) using simple hydrothermal method. The as-synthesized material was confirmed by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX) techniques, scanning electron microscopy (SEM). In addition, V2O5 NFs was used as an electrocatalytic performance towards the electro-oxidation of Adenine. Interestingly, V2O5 NFs modified electrode (V2O5 NFs/SPCE) showed an excellent electrocatalytic activity towards Adenine with lower detection limit (0.013 mu M), wide linear ranges (0.5 to 512 mu M) and the higher sensitivity about 8.5333 mu A mu M-1 cm(-2). Furthermore, V2O5 NFs/SPCE was also demonstrated good recovery even in real human urine samples. This study opens a new window for the trace level identification of biological molecules in real samples.
