TL;DR: In this paper, the electrochemistries of antimony and simple hydrocarbons were examined in HF/SbF/sub 5/. From cyclic voltammetric data, Sb(V) appears to be a strong oxidizing agent in the super acid media, capable of oxidizing polymeric material containing three or more carbon atoms.
Abstract: The electrochemistries of antimony and simple hydrocarbons were examined in HF/SbF/sub 5/. From cyclic voltammetric data, Sb(V) appears to be a strong oxidizing agent in the super acid media, capable of oxidizing hydrocarbons containing three or more carbon atoms. It is therefore reasonable that the Sb(V) reduction process supplies the energy required for the super acid ''catalyzed'' condensation of saturated hydrocarbons, confirming suggestions already in the literature. The anodic oxidation of aromatic hydrocarbons was also examined in acidic fluoride media (HF/SbF/sub 5/ and HF/NaF). It is observed that the oxidation of benzene results in the deposition of electronicallyconducting polymeric material on the anode. The material has been identified as p-polyphenylene. The conductivity of the polymer is assumed to result from the formation of a charge-transfer complex between the partially oxidized polymer and the Lewis acid.

TL;DR: In this paper, a molybdenum/vanadium-based oxide catalyst was used to produce acrylic acid using ammonium metavanadate and at least one vanadium oxide in which the valency of vanadium is larger than 0 but smaller than 5.
Abstract: Acrylic acid can be produced efficiently by subjecting acrolein to catalytic gas-phase oxidation in the presence of a molybdenum/vanadium-based oxide catalyst prepared by using particular substances as the raw materials of the individual metal elements constituting the catalyst. A preferable example of such a catalyst is prepared by using, as the raw materials of vanadium, ammonium metavanadate and at least one vanadium oxide in which the valency of vanadium is larger than 0 but smaller than 5; as the raw material of copper, copper nitrate; and, as at least part of the raw material(s) of antimony, at least one antimony oxide in which the valency of antimony is larger than 0 but smaller than 5.

TL;DR: In this paper, it has been observed that an optimum amount of antimony doping in tin dioxide gives the maximum gas sensitivity, and with the addition of palladium (upto 2 ¼ ) the resistance of SnO2 sensors has been found to increase, although the gas sensitivity maximum is achieved at 0.5 ¼.
