Bridging electrochemistry and heterogeneous catalysis

  • Costas G. Vayenas


The discovery of the effect of the electrochemical promotion of catalysis (EPOC) or non-Faradaic electrochemical modification of catalytic activity (NEMCA effect) is described together with the key steps of its exploration at high pressure and high vacuum and its rationalization via electrochemical and surface science techniques. Recent attempts for its practical utilization are also surveyed.

I am deeply indebted to a lot of people for the work outlined in this paper.First, to my PhD thesis advisers, H. Saltsburg and W.D. Smith, at the University of Rochester and also to Professor A. Acrivos who recommended me to MIT. Second, to my PhD students at MIT and Patras who in chronological order were J. Michaels, M. Stoukides, M. Manton, I. Yentekakis, S. Neophytides, S. Bebelis, V. Papadakis, E. Kolyfetis, D. Spartinos, P. Tsiakaras, A. Ioannides, C. Karavasilis, H. Karasali, Yi Jiang, C. Pliangos, A. Kaloyannis, M. Makri, C. Yiokari, D. Tsiplakides, Y. Bafas, C. Raptis, T. Bathas, A. Katsaounis, A. Frantzis, S. Balomenou, Y. Constantinou, A. Giannikos, D. Archonta, C. Koutsodontis, F. Sapountzi, S. Souentie, D. Presvytes, M. Tsampas, and V. Papaioannou. Third, to my MS students at MIT, B. Lee, R. Farr, J. Mulready, C. Teague-Sigal, and P. Debenedetti. Fourth, to my postdoctoral coworkers in Patras, who included many former PhD students but also Drs. P. Petrolekas, O. Mar’ina, Jiang Yi, S. Brosda, Xingang Li, and A. Hammad. Fifth, to the colleagues with whom we have collaborated in the EPOC area over the years starting from Richard Lambert, Christos Comninellis, and Nikola Anastasijevic and continuing with Milan Jaksic, Gary Haller, Carlos Cavalca, Fritz Kalhammer, Philippe Vernoux, György Fóti, Ezequiel Leiva, Gianfranco Pacchioni, Xenophon Verykios, Spyros Ladas, Ian Metcalfe, Vladimir Sobyanin, Eugene Smotkin, Ilan Riess, Leo Kriksunov, Jose Luis Valverde, and Elena Baranova. Sixth, to our brilliant and invaluable secretary Ms. Chryssa Pilisi who has contributed enormously to our effort over the years. Without her, we would have never made it that far with EPOC. Last but not least, to my parents, family, and adorable children for their patience and encouragement over the years.
