Disclosed is a catalyst comprising at least one catalytically active element and one co-catalyst. The catalyst may be used to increase the rate of chemical reaction, to change its selectivity, or to reduce the overvoltage. These catalysts can be useful in particular various chemical reactions, including electrochemical conversion of CO 2. Chemical methods and devices that use this catalyst is also disclosed, for example CO, OH -, HCO -, H 2 CO, (HCO 2) -, H 2 CO 2, CH 3 OH, CH 4, C 2 H 4, Process for producing CH 3 CH 2 OH, CH 3 COO − , CH 3 COOH, C 2 H 6 , O 2 , H 2 , (COOH) 2 , (COO − ) 2 and specific elements, ie A CO 2 sensor is also disclosed. |
