Abstract

Using a surfactant-mediated method (surfactant based on cetyltrimethyl ammonium bromide, CTAB) V2O5 nanorod and nanoparticles have been successfully prepared. Morphologies of V2O5 nanostructures can be controlled by applying different precursors and by varying reaction conditions within the CTAB soft template. With ammonium metavanadate and sulfuric acid as precursors, nanoparticles are synthesized in the size range of 45-160 nm. Precursors of vanadyl sulfate hydrate and sodium hydroxide yield vanadium pentoxide nanorods with diameters of 30-90 nm and lengths of 260-600 nm. The resulting products are characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), variable pressure scanning electron microscopy (VPSEM) and X-ray photoelectron spectroscopy (XPS). Temperature programmed reduction (TPR) is included to test catalytic performance. The results show that V2O5 nanoparticles and nanorods achieve better catalytic performance compared to bulk V2O5, i.e. lower onset temperature, workability at lower temperatures, and higher H2 consumption (μmol/g).
