摘要：
This study summarizes the effect of the electrochemical promotion of catalysis (EPOC) by using potassium conductors in environmental catalytic reactions applied to the removal of several automotive pollutants, such US CO, C3H6 and nitrogen oxides (N2O and NOx). It has been shown the extraordinarily potential of using Pt/K-beta Al2O3 in a wide variety of environmental reactions (oxidation, reduction), activating the catalyst at lower reaction temperatures and decreasing the inhibitory effect of poisons such as water in the reaction atmosphere. in addition, a new application of potassium conductors-based electrochemical catalysts has been developed for the NOx storage/reduction process (NSR). The idea of coupling catalysis and solid-state electrochemistry on this process would allow to improve and simplify the current NSR technology. Finally, the results have been obtained under reaction conditions compatible with the treatment of automotive exhaust emissions. This demonstrates the potential for the practical use of the phenomenon of electrochemical promotion by using potassium conductors on this kind of process. (C) 2009 Elsevier B.V. All rights reserved.
