Abstract:
1. A method for electrochemical production of butanol, comprising: (A) introducing water to a first compartment of a first electrochemical cell, said first compartment including an anode; (B) introducing carbon dioxide to a second compartment of said first electrochemical cell, said second compartment including a solution of an electrolyte, a catalyst, and a cathode; (C) applying an electrical potential between said anode and said cathode in said first electrochemical cell sufficient for said cathode to reduce said carbon dioxide to an intermediate product mixture; (D) separating a two-carbon intermediate from said intermediate product mixture; (E) introducing said two-carbon intermediate to a second electrochemical cell, wherein (i) said second electrochemical cell including an anode in a first cell compartment and a cathode in a second cell compartment and (ii) said cathode reducing said two-carbon intermediate to a product mixture; and (F) separating butanol from said product mixture.
