Abstract

Lately there has been much interest in synthesizing characterizing new vanadium oxide host/ guest compounds. These compounds have open structures and the ability to intercalate atoms or molecules. They may be used as catalysts, molecular sieves, absorbents and energy storage devices. We are studying the synthesis and characteristics of vanadium oxides nanotubes. This experiment has been synthesized by sol-gel methods and based on hydrothermal treatment at temperature 150°C-180°C. For characterization of samples, SEM, XRD, TEM, and FT-IR were used. Also, we consider the effect of ultrasonic on the formation of vanadium oxides nanotubes. Results show that diameter of the vanadium oxides nanotubes are varied from 15 to 25 nm (inner diameter) and 50 to 90 nm (outer diameter). In this research, vanadium oxide nanotubes had been synthesized via gelation of V2O5 and ethanol as solvent followed by hydrothermal treatment for one (1) to seven (7) days at 180ºC. The main objective of the study is to produce good quality VOX-NTS at a fastest synthesis time.
