Abstract
Electrochemical CO<sub>2</sub> reduction reaction (CO<sub>2</sub>RR) can enable the production of fuels and chemicals from CO<sub>2</sub> emissions. Direct flue gas conversion can address the emissions from hard-to-abate sectors, including cement, steel, and power generation industries. Such integration with SCO<sub>2</sub>RR can also decarbonize the petrochemical industry and eliminate separation and purification steps. Here, recent progress and emerging opportunities for transformative flue-gas-tolerant systems for producing fuels and chemicals are reviewed. The review begins by analyzing recent progress in direct flue gas conversion and highlighting emerging micro-reaction environment features. Next, performance degradation mechanisms associated with flue gas conversion in CO<sub>2</sub>RR systems are discussed. Following this, the bicarbonate reduction reaction (BRR) and CO<sub>2</sub>RR from amine-based capture as emerging strategies for high-rate, selective, and stable electrosynthesis of chemicals from feeds containing low CO<sub>2</sub> concentrations are highlighted. Finally, the mitigation of flue gas impurities such as oxygen, sulfur oxides, and nitrogen oxides, is discussed, and perspectives for emerging opportunities are shared.
