Abstract
An electrocatalytic device for carbon dioxide conversion includes an electrochemical stack comprising a series of cells with a cathode with a Catalytically Active Element metal in the form of supported or unsupported particles or flakes with an average size between 0.6 nm and 100 nm. The reaction products comprise at least one of CO, HCO−, H2CO, (HCOO)−, HCOOH, CH3OH, CH4, C2H4, CH3CH2OH, CH3COO−, CH3COOH, C2H6, (COOH)2, (COO−)2, and CF3COOH.
Claims18

- (a) an anode comprising a quantity of anode electrocatalyst;
- (b) a cathode comprising a quantity of cathode electrocatalyst;
- (c) a source of CO2 directed to said cathode;
- (d) a membrane interposed between said anode and said cathode, wherein:
- (i) said cathode electrocatalyst is in the form of unsupported particles or particles supported on an electrically conductive support;
- (ii) said particles have an average size between 0.6 nm and 100 nm;
- and
- (iii) said cathode electrocatalyst converts CO2 to a carbon-containing reaction product.
