Spherical porous vanadium pentoxide (V 2 O 5 ) phase is synthesized by a spray-pyrolysis method followed by heat-treatment, as confirmed by powder X-ray diffraction. Under high-resolution electron microscope observation, the as-prepared particles are spherical and porous, with uniform particle size.
In this paper, a cerium dioxide (CeO 2 ) modified titanium dioxide (TiO 2 ) nanotube array film was fabricated by electrodeposition of CeO 2 nanoparticles onto an anodized TiO 2 nanotube array. The structural investigation by X-ray diffraction, scanning electron microscopy and transmission electron
## Abstract Vanadium oxide nanorods were prepared by a hydrothermal route and then tested as a transducer for a resistiveβtype gas sensor. The importance of control of pH and pressure during the synthesis of 1D crystals of vanadium oxide was demonstrated for the V~2~O~5~/ethanol mixture, which serv
