Abstract

In this proposed work, nanoparticles of vanadium pentoxide (V2O5) and vanadium pentoxide with rGO have been fruitfully synthesized through a suitable hydrothermal method at a constant temperature (180○C).As synthesized V2O5 nano particles were characterized, and fabricated as a gas sensor by coating the synthesized material on ITO glass substrate. The NH3gas sensing properties of the fabricated sensors were carried out. Structural investigation of the same showed that V2O5 nanoparticles formed have orthorhombic crystal phase and the size of the nanorods was found to be 90 nm. The gas sensor studies revealed a higher sensing response at 2500C and demonstrated excellent gas sensing properties toward 1-3.2 ppm NH3 gas. It also exhibited a good selectivity, sensitivity and stability, with rapid response/recovery time, and a linear relationship between the response and the target gas concentration. In particular, the sensing performance of the V2O5 gas sensor was trained through MATLAB for regression analysis, which suggests the permissible R2 value of 0.88 of a prompt gas sensing response.
