Catalytic Effect of Nb2O5 in MgH2-Nb2O5 Ball-Milled Composites
We report a study on the desorption properties, crystallography and chemical state of MgH2 and 1 mol% Nb2O5 ball-milled composites. Desorption temperatures of the composites decreased with increase of ball-milling time. Size of MgH2 crystallites decreased during ball-milling. Reduction of Nb2O5 after ball-milling was confirmed by tracing the chemical state of Nb and was further supported by TEM...
متن کاملSingle-crystalline nanoporous Nb2O5 nanotubes
Single-crystalline nanoporous Nb2O5 nanotubes were fabricated by a two-step solution route, the growth of uniform single-crystalline Nb2O5 nanorods and the following ion-assisted selective dissolution along the [001] direction. Nb2O5 tubular structure was created by preferentially etching (001) crystallographic planes, which has a nearly homogeneous diameter and length. Dense nanopores with the...
متن کاملElectrochemical Degradation of Chlorpyrifos in Aqueous Solutions Using G/nb2o5 and Nb/nb2o5 Electrodes
Glass/Nb2O5 and Nb/Nb2O5 electrodes were prepared by electrodeposition and used as anodes for electrochemical degradation of chlorpyrifos (CPF) in aqueous solution. Different operating conditions and factors affecting the treatment process including current density, temperature, initial concentration of chlorpyrifos, pH, conductive electrolyte and time of electrolysis were studied and optimized...
متن کاملDevelopment of AlN and TiB2 Composites with Nb2O5, Y2O3 and ZrO2 as Sintering Aids
The synthesis of AlN and TiB2 by spark plasma sintering (SPS) and the effect of Nb2O5, Y2O3 and ZrO2 additions on the mechanical properties and densification of the produced composites is reported and discussed. After the SPS process, dense AlN and TiB2 composites with Nb2O5, Y2O3 and ZrO2 were successfully prepared. X-ray diffraction analysis showed that in the AlN composites, the addition of ...
متن کاملAnodic formation of high aspect ratio, self-ordered Nb2O5 nanotubes.
In the present work, we demonstrate the feasibility to form an aligned Nb(2)O(5) nanotube layer by self-organizing anodization of Nb in a NH(4)F-glycerol electrolyte. In order to achieve a nanotubular rather than a nanoporous layer, careful optimization of the anodization electrolyte is required. We show that only in a narrow window of electrolyte parameters highly aligned nanotubes of 50 nm in...
