Temperature, pressure, and adsorption‐dependent redox potentials: I. Processes of CO ₂ reduction to value‐added compounds

Catalytic conversion of carbon dioxide (CO2) into value-added chemicals and fuels can not only mitigate global warming but also alleviate the energy crisis caused by fossil fuel depletion. Redox potential is a key thermodynamic quantity CO2 reduction reactions, while currently, standard (25°C, 1 atm, M) available for application. Herein, it first time to report influence temperature (0–1000°C), pressure (1–100 atm), molecular adsorption on redox potentials series reactions form monoxide, formic acid, formaldehyde, methanol, methane, oxalic acetic acetaldehyde, ethanol, ethylene, ethane. Although almost all gas-phase aqueous-phase decrease with at an increased rate increase decreased rate, adsorption-state are sensitive no smaller than potentials. Significant differences up 2.35 V regard would directly affect thermodynamics kinetics reactions. This will serve as enriched database that allows use under actual experimental conditions.
