    摘要: An electrochemical device comprises an anode and a cathode. An electrocatalyst mixture is placed between said anode and cathode. The electrocatalyst mixture comprises at least one Catalytically Active Element and, separately, at least one Helper Catalyst comprising an organic molecule, an organic ion, or a mixture of organic molecules and organic ions. The electrocatalyst mixture electrochemically converts carbon dioxide to one or more carbonaceous reaction products via the reaction: CO2+2e−+2H+→carbonaceous reaction products, at overpotentials of 0.9 V or less.

    摘要: An electrochemical conversion method for converting at least a portion of a first mixture comprising hydrocarbon to C2+ unsaturates by repeatedly applying an electric potential difference, V(τ1), to a first electrode of an electrochemical cell during a first time interval τ1; and reducing the electric potential difference, V(τ1), to a second electric potential difference, V(τ2), for a second time interval τ2, wherein τ2≦τ1. The method is beneficial, among other things, for reducing coke formation in the electrochemical production of C2+ unsaturates in an electrochemical cell. Accordingly, a method of reducing coke formation in the electrochemical conversion of such mixtures and a method for electrochemically converting carbon to C2+ unsaturates as well as an apparatus for such methods are also provided.
