Hydrothermal synthesis and characterization of mesoporous rod-like hybrid organic-inorganic nanocrystalline based vanadium oxide

Abstract

Abstract We describe a simple route to mesoporous rod-like nanocrystalline of hybrid organic–inorganic based vanadium oxide through the hydrothermal method using V 2 O 5 as vanadium source and 2-phenylethylamine as reducing and structure-directing agent. Techniques X-ray diffraction (XRD), scanning electron microscope (SEM), thermal analysis (TG-DTA), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, UV–visible spectroscopy and nitrogen adsorption/desorption isotherms (BET) have been used to characterize the structure, morphology and the texture of the samples. The nanorods are up to several hundred nanometers in length, the width and the thickness are 280–300 and 60 nm, respectively. The molar ratio plays a key role on the structure and the morphology of the materials.
