Effect of the preparation method and of the vanadium content on the physicochemical and surface properties of vanadium–magnesium-based catalysts for the selective oxidation of n -butane

Samira Slyemi, Juliette R Blanchard, Siham Barama, Akila Barama, Hassiba Messaoudi, Sandra Casale, Christophe Calers, Zaher Ihdene

Two series of V–Mg–O catalysts with vanadium contents of 30 and 60 wt % were synthesized using sol–gel (SG) and wet impregnation (IMP). The elaborated catalysts were characterized by X-ray diffraction, Fourier transform infrared, X-ray fluorescence, Brunauer–Emmett–Teller, NH3–temperature-…

Electrochemistry of a new carbon-rich fluorine-doped tin oxide (CFTO) material as a powder electrode in chloride electrolytes

Chantal Cachet, Hubert Cachet, B Jousseaume, T Toupance, Vincent Vivier

The electrochemical behavior of a conductive carbon-rich fluorine-doped tin oxide (CFTO) powder synthesized via the sol–gel process was investigated by studying the chloride oxidation reaction in aqueous media with the help of a cavity microelectrode (CME) without any binding additive. This new…
