Effect of the templating cationic surfactant assisted with Vanadium Pentoxide on the synthesis and structure of V2O5 as tailored Electrode material

Abstract

A facile synthesis of inimitable hierarchical one-dimensional (1D) V2O5 nanorods were successfully developed by simple hydrothermal process. In this work, the effects of the Nature of the Tem-plating Surfactant cetyltrimethylammonium bromide (CTAB) were investigated with atypical concentration in the synthesized samples. The effects of a number of factors, such as the nature of the surfactant, the pH, and the vanadium/ctab  ratio in the formation of nanorods V2O5 phases were examined by X-ray diffraction, Thermo-gravimetric , differential temperature , Brunauer-Emmett-Teller , Barret-Joyner-Halenda, scanning electron microscope, transmission electron microscope, FT- infrared, FT-Raman and UV–vis reflectance studies exhibit characteristic  of ortho-rhombic V2O5. It was found that the ordered arrangement crystallinity of the pores was strongly dependent on the vanadium/ctab ratios in the initial batches; too large ratios were unfavorable to the crystallinity. The optimum vanadium/ctab ratio regarding the crystallinity was found to be in the range 1:0.1. The calculated BET specific surface area of V2O5-ctab small ratio sample is 10.52 m2g-1, which is much higher than the surface areas of both V2O5-ctab too large (9.37 m2g-1) and V2O5-free (7.5 m2g-1) samples. High specific surface area and mesoporous nanorods-like morphology of V2O5-ctab are the essential factors to show better performance as an electrode material.
