“…This also agrees with the observation that the CO 2 conversion stronger dependence on the effect of the electric field than the nature of the catalyst . These results also agree with the observations in NEMCA of CO 2 hydrogenation in that a negative (reduced) potential increased the selectivity and reaction rate to CO, and a positive (increased) potential increased the selectivity and reaction rate to CH 4 …”

“…Urquhart et al used other K + -conductor solid electrolyte (K-βAl 2 O 3 ) in Fischer-Tropsch reaction studies under both atmospheric [21] and high pressure [22], and de Lucas-Consuegra et al introduced the use of this kind of ion-conducting catalyst support for the electrochemical promotion of Pt in CO [23] and propylene [24] oxidation, as well as in NO x reduction reactions [25,26]. More recent alkaline electrochemical promotion studies on CO 2 hydrogenation [27][28][29][30] and methanol conversion reactions [31][32][33] should also be highlighted. Additionally, in order to understand the mechanism of the phenomenon of electrochemical promotion of catalysis with both anionic and cationic conductors, a wide variety of characterization techniques have been used in the fields of catalysis (e.g., TPD, TPO, or work function measurement), electrochemistry (e.g., cyclic/linear sweep voltammetry or impedance spectroscopy), and surface science (e.g., XPS, UPS, SPEM, or STM) [3].…”

From this pioneer work, Na + -conductors have been widely employed in many catalytic systems such as ethylene [9,10], CO [11], propane [12] and propylene oxidation [13], NO reduction [14][15][16], Fischer Tropsch synthesis [17], or hydrogenation of benzene [18] and CO 2 [19].…”

“…Υπάρχει όμως και μια πληθώρα μελετών που αφορούν στην ηλεκτροχημική ενίσχυση της αντίδρασης αυτής, ιδιαίτερα τις τελευταίες δεκαετίες, με πολύ σημαντικά αποτελέσματα. Συγκεκριμένα έχουν γίνει μελέτες στο παρελθόν σε καταλύτες Cu, Rh, Pt και σε Ni και Ru, εναποτεθειμένους σε YSZ και β-Αl2Ο3 [16,133,136,137,145,[196][197][198][199].…”

“…Στις περιπτώσεις αυτές τα μοναδικά προϊόντα της αντίδρασης ήταν το CO και το CH4 σε θερμοκρασίες λειτουργίας από ~300 -480 o C [198,200]. Σε μελέτη των Theleritis et al με καταλύτη Ru/YSZ, η θερμοκρασία κυμάνθηκε μεταξύ 200 -300 o C [133].…”
