Room temperature ethanol sensors using V2O5 nanoparticles annealed at different temperatures
In this work V2O5 nanoparticles (NPs) were synthesized via a facile Pechini sol-gel route from NH4VO3. The as-synthesized amorphous NPs were annealed at three different temperatures, i.e. 350, 450 and 550 °C for 2 h, to study the effect of annealing temperature on the gas sensing performance of the...

| description | In this work V2O5 nanoparticles (NPs) were synthesized via a facile Pechini sol-gel route from NH4VO3. The as-synthesized amorphous NPs were annealed at three different temperatures, i.e. 350, 450 and 550 °C for 2 h, to study the effect of annealing temperature on the gas sensing performance of the crystalline V2O5 NPs. Different characterizations were performed on the synthesized materials to explore their chemical, morphological and structural features. Ethanol gas sensing properties of the annealed V2O5 NPs were explored at room temperature with a response of 20 to 1600 ppm ethanol gas. The sensor annealed at 450°C, indicated the highest sensing response of ~37% to 1600 ppm ethanol vapour along with good selectivity and repeatability. The boosted sensing properties of the optimized gas sensor were related to the optimization of crystallinity and particle size after annealing at 450°C. Thus, proper choice of annealing temperature is important to realize the sensors with high sensing performance. |
