| Abstract: |
The electrochemically decoupled reduction of CO2 using nickel cyclam as a homogeneous catalyst and chromium propanediaminetetraacetate (PDTA) as a reductive redox mediator is reported in aqueous media. Uniquely, the Ni cyclam catalyst, known for exclusive homogenous CO production instead gives a mixed product selection of HCOO(H) and CO depending on the supporting electrolyte composition, with KHCO3 favouring CO and KCl favouring HCOO(H). The CrPDTA shows no conventional electrochemical booster effects, but exclusively reacts with the Ni cyclam when generated as a bulk Cr(II) species. [ABSTRACT FROM AUTHOR] |
