“…The need for an effective control of hazardous auto exhaust emissions led several research groups to use O 2− SECRs for the reaction of NO x with reducing compounds such as CO, ,, CH 4 , − C 2 H 4 , ,, C 3 H 6 , ,− ,,,− ,,, and NH 3 . , In most of the above works, NO x was fed at the cathode, together with the reducing compound, and the effect of O 2− pumping on the reaction rate was studied. The highest NEMCA effect was observed during the reduction of NO by C 3 H 6 on Rh when the rate enhancement factor (ρ) reached values as high as 150 …”

Solid electrolytes have found applications in several areas, including (a) sensors, (b) separators, (c) solid oxide fuel cells, and (d) solid-state batteries. In addition, solid electrolytes have been used in the construction of solid electrolyte cell reactors (SECRs), in which heterogeneous catalytic reactions have been studied. Also, SECRs have been used as chemical cogenerative fuel cells, i.e., for the simultaneous production of electricity and useful compounds. In the present work, a survey of the studies conducted in SECRs is presented. The fundamental operating principles, results in technologically important reactions, and the hurdles that should be overcome to bring SECRs into industrial practice are discussed.

“…6 gewählten Darstellung verhalten sich beide Grössen praktisch spiegelbildlich zueinander. Dieses Verhalten ist erstmals von Brück [11] [12] bei der Untersuchung der selektiven katalytischen Reduktion von Stick-oxiden an (Vanadium-oxid/Titanoxid)-Katalysatoren beobachtet worden, tritt aber ebenfalls bei partiellen Oxidationen auf, wie Estenfelder und Lintz [22] bei der Bildung von Acrylsäure an oxidischen Katalysatoren feststellen konnten.…”

Dedicated to Professor AndreÂ M. Braun on the occasion of his 60th birthdayIn situ Characterization of Vanadia ± Titania Catalysts in the Partial Oxidation of o-Xylene Different doped vanadia ± titania catalysts have been studied by combined kinetic and electrochemical measurements. Solid electrolyte potentiometry (SEP) allowed the determination of the oxidation state of the oxides under working conditions. The results show that there is no chemisorption equilibrium between the oxide and the oxygen in the gas phase. Further, the results allow to differentiate between the influence of dopants on the rate of oxygen uptake by and the rate of oxygen release from the oxidic catalyst. Doping with Li or Cs leads to a diminuition of the catalytic activity due to the decrease of the rate of oxygen transfer from the catalyst to the gaseous oxygen acceptor. Neither alcali doping nor the addition of Pd, Sn, or Bi improves the selectivity of the formation of phthalic anhydride.
