The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide (CO 2) to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization. [1]
Thermodynamic potentials for the reduction of CO 2 to various products is given in the following table versus NHE at pH = 7. Single electron reduction of CO 2 to CO 2 − radical occurs at E° = −1.90 V versus NHE at pH = 7 in an aqueous solution at 25 °C under 1 atm gas pressure.

It is the disproportionation of carbon monoxide into carbon dioxide and graphite or its reverse: [1] 2CO ⇌ CO 2 + C Boudouard-Equilibrium at 1 bar calculated with 2 different methods Standard enthalpy of the Boudouard reaction at various temperatures. The Boudouard reaction to form carbon dioxide and carbon is exothermic at all
Where is the standard reduction potential of the half-reaction expressed versus the standard reduction potential of hydrogen. For standard conditions in electrochemistry (T = 25 °C, P = 1 atm and all concentrations being fixed at 1 mol/L, or 1 M) the standard reduction potential of hydrogen E red H+ ⊖ {\displaystyle E_{\text{red H+ ...
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.

The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO 2) and hydrogen (H 2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat. CO 2 is usually reduced by H 2 to carbon in presence of a catalyst (e.g. iron (Fe)) and requires a temperature level of 530–730 °C (986–1,346 °F). [1] [2]
