Temperature, pressure, and adsorption dependent redox potentials: III. Processes of CO conversion to value‐added compounds

Carbon monoxide (CO) is a primary air pollutant and poisonous species for human beings, animals, some catalytic reactions. Meanwhile, CO also versatile feedstock in the chemical industry to produce high-value chemicals clean fuels, which has stimulated extensive research interests exploiting efficient conversion processes. Redox potential key thermodynamic quantity these processes whereas only standard reduction potentials at 25°C 1 atm are currently available. Herein, it first time report effects of temperature (0–1000°C), pressure (1–100 atm), adsorption on redox 18 reactions form carbon dioxide, methane, straight-chain alkanes (ethane, propane, butane), light olefins (ethylene, propylene, butylene), benzene, alcohols, aldehydes, acids, dimethyl ether, based theoretical calculations. It was noticed that gas-phase, aqueous-phase, adsorption-state decrease with increasing an increased rate while they show different responses change. Namely, gas-phase most aqueous-phase increase gradually declined rate, not influenced by pressure. Most importantly, significant differences up 2.06 V under varied conditions highlight necessity applying operando
