The effect of synthesis duration on the formation of Non-Stoichiometric Tungsten Oxide (W18O49)

This study investigates the synthesis duration (24 h and 48 h) effect on the structural properties ofunique non-stoichiometric structure of tungsten oxide (W18O49). Oxygen-vacancy-rich W18O49 nanoparticleshave been successfully synthesized using a facile one-pot hydrothermal method. The properties of sampleswere characterized by X-ray diffraction (XRD), Scanning electron microscope (FESEM) and energydispersiveX-ray spectroscopy (EDS). Also, the growth mechanism of samples is explained. The crystallitesize of the synthesized samples increased over time increasing (from 37.23 nm to 39.17 nm). Theenhancement of synthesis duration resulted in the formation of nanorods that are thicker, longer, and stucktogether.
