Dependence of V₂O₅ Nanorods Properties on Substrate Type Prepared by Simple Hydrothermal Method

Abstract

V 2O5 (Vanadium pentoxide) nanorods were prepared onto various substrates by using simple hydrothermal method. The structural characteristics of the V 2O5 nanorods (NRs) have been examined via using XRD diffraction analysis. The effects of the various substrates on the morphological characteristics of V 2O5 NRs were investigated by using field emission scanning electron microscopy (FESEM) technique. The XRD results show that the preferred orientation along (001) plane. Raman spectra indicate that glass substrate has optimum results due to the size and number of the nanorods with lower defects. It can be found from the absorbance of the glass substrate increases compared with the other substrates.

Hydrothermal Carbonization of V2O5 Nanowires into Aerogels for Excellent Green Electromagnetic Interference Shielding

“…The peaks in the CVO composite gel and VO aerogel are identical, and the spectrum is symmetric with the reported Raman modes for V 2 O 5 •nH 2 O. 28,29 The dominant peak at 142 cm −1 corresponds to the V−O−V chain. The two peaks at 284 and 408 cm −1 are associated with the bending vibration of the V�O bonds, and 991 cm −1 is assigned to the V�O stretching vibrations.…”

Outstanding electromagnetic interference shielding performance in hydrothermally derived vanadium pentoxide–polyaniline aerogels

“…The peaks of pure V 2 O 5 aerogel are symmetric with the reported Raman modes for V 2 O 5 ÁnH 2 O. [44][45][46] The dominant peak at 140 cm À1 corresponding to V-O-V chain vibrations indicates the layer structure of the V 2 O 5 precursor. The two peaks at 281 and 405 are associated with the bending vibration of the VQO bonds, and 991 cm À1 is assigned to the VQO stretching vibrations.…”

“…On the other hand, the shoulder peaks obtained at 483 and 304 cm −1 belong to bending vibrations of V–O–V (doubly coordinated oxygen) and V 3 –O (triply coordinated oxygen) type, respectively. 28,29 The peaks positioned at 526 and 704 cm −1 correspond to the stretching vibrations of triply co-ordinated oxygen (V 3 –O) and doubly co-ordinated oxygen (V 2 –O), respectively. Finally, the Raman shift present at 995 cm −1 is due to the terminal oxygen (V 5+ O) stretching mode.…”

“…Finally, the Raman shift present at 995 cm À1 is due to the terminal oxygen (V 5+ QO) stretching mode. 29,30 In addition, BET analysis was also conducted to evaluate the specific surface area and porosity of the material. As depicted in Fig.…”
