Description
In recent years, there has been substantial progress in the development of nanomaterials for gas sensing applications. One of the key challenges in this field lies in selecting an appropriate sensing layer, along with optimising the device structure, fabrication method, and morphology to fully exploit the sensing capabilities of the material. This work presents the synthesis of pristine V₂O₅, as well as 1, 3, and 5 wt.% Ag-doped V₂O₅ using ammonium metavanadate (NH4VO3, 99%) and silver nitrate (AgNO3) as precursors through a hydrothermal method. The samples were characterized using Scanning Electron Microscopy (SEM), which revealed that pristine V₂O₅ formed irregular structures. The Incorporation of Ag led to the formation of nanorods, which significantly improved with the dopant concentration. Energy-dispersive X-rays (EDX) confirmed the successful incorporation of Ag into the V₂O₅. These results demonstrate that Ag doping significantly alters the morphological properties of V₂O₅, resulting in nanorods, which are believed to be a promising hierarchical structure for gas sensing applications. Further characterisation using X-ray diffraction (XRD) shows more interesting results.
