Cobalt-coordinated tetracyanoquinodimethane (R-CoTCNQ) shows promise as a catalyst for carbon dioxide electroreduction (CO2ERR). First principles calculations predict it can yield formic acid or formaldehyde, depending on electrode potential.
Area of Science:
- Computational Chemistry
- Materials Science
- Electrochemistry
Background:
- Carbon dioxide electroreduction (CO2ERR) is crucial for sustainable energy.
- Developing efficient catalysts is key to improving CO2ERR performance.
- Cobalt-based materials are actively researched for CO2ERR applications.
Purpose of the Study:
- To investigate cobalt-coordinated tetracyanoquinodimethane (R-CoTCNQ) as a potential CO2ERR catalyst.
- To determine the accuracy of different computational functionals for describing R-CoTCNQ.
- To explore reaction pathways and products of CO2ERR using R-CoTCNQ.
Main Methods:
- First principles calculations were employed.
- The meta-GGA r2SCAN functional was used for accurate spin property description.
- Free energy pathways for CO2ERR were calculated for R-CoTCNQ and supported R-CoTCNQ.
Main Results:
- R-CoTCNQ can catalyze CO2ERR, producing HCOOH or HCHO based on electrode potential.
- Supported R-CoTCNQ on diamond surfaces showed similar reaction pathways.
- Boron-doping in the diamond support slightly improved the CO2ERR pathway.
Conclusions:
- R-CoTCNQ is a promising catalyst for CO2ERR.
- Supported R-CoTCNQ offers a high specific area of active cobalt sites.
- Further experimental investigation of R-CoTCNQ catalysts is warranted.

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
