Abstract
The present disclosure provides methods, compositions, devices, systems and uses that pertain to the electrochemical reduction of CO2 to CO. The application presents a class of electrodes, incorporating molecular catalysts in nanostructures, for robust and efficient electrochemical systems, specifically, selective and robust hybrid electrodes, by incorporating a rhenium (Re) catalyst into the structure of highly porous heterogeneous materials. These electrodes can be scaled up to desired manufacturing dimensions due to their robust nature and methods of preparation.
Claims26
A composition comprising a rhenium catalyst and a carbon support wherein:
- the rhenium catalyst has a formula of Re(4,4′-R-2,2′-bipyridine)(CO)3X;
- R is an electron donating group or an electron withdrawing group;
- X is a halogen, acetonitrile, CH3CN(OTf), or Py(OTf);
- and
- wherein the rhenium catalyst is dispersed on a surface of the carbon support.
