Green Synthesis of Nanoscale Nb2O5 Particles, their Characterization and use in the Modification of an Electrochemical Sensor

An alternative green and new method was proposed for preparing Nb2O5 nanoparticles (NPs). The nano-sized particles were characterized using FT-IR, XRD, EDX, SEM and VSM techniques. The best sample in terms of dimensions was 50-70 nm in size. In order to investigate its electrochemical application, it was used to detect uric acid and CV, DPV and EIS techniques were applied for this purpose. Detection limit 3 μM was achieved using this method for of uric acid.
