“…In contrast, a gas‐phase AEM electrolyzer can effectively counteract the cathodic acidification that accompanies the employment of CEM, in which water dissociation occurs at the cathode, providing protons H + for CO 2 RR and consequential OH − passage from the cathode to the anode via AEM (Figure 12c). [ 288,290–292 ] Therefore, the competitiveness of the HER is dramatically weakened in the gas‐ phase AEM electrolyzer, and the catalytic capacity of the CO 2 RR is significantly boosted compared to that of the gas‐phase CEM electrolyzer, which can be further demonstrated by the contrasting catalytic performance of the AEM‐based and CEM‐based gas‐phase electrolyzers under the same experimental conditions.

Electrochemical carbon dioxide reduction reaction (CO2RR) driven by renewable energy shows great promise in mitigating and potentially reversing the devastating effects of anthropogenic climate change and environmental degradation. The simultaneous synthesis of energy‐dense chemicals can meet global energy demand while decoupling emissions from economic growth. However, the development of CO2RR technology faces challenges in catalyst discovery and device optimization that hinder their industrial implementation. In this contribution, we provide a comprehensive overview of the current state of CO2RR research, starting with the background and motivation for this technology, followed by the fundamentals and evaluated metrics. We then discuss the underlying design principles of electrocatalysts, emphasizing their structure–performance correlations and advanced electrochemical assembly cells that can increase CO2RR selectivity and throughput. Finally, we look to the future and identify opportunities for innovation in mechanism discovery, material screening strategies, and device assemblies to move toward a carbon‐neutral society.This article is protected by copyright.

“…89 BPM is composed of an anion exchange layer, a cation exchange layer and a catalytic layer in between. 90 The high potential gradient will drive H + to the cathode through the cation exchange layer and OH − to the opposite. Therefore, the pH difference between the anode and cathode due to the BPM technique provides more possibilities in the paired organic electrolysis.…”

“…Electrochemical technologies such as water electrolysis [1][2][3][4] , CO2 conversion 5,6 , and carbon removal [6][7][8][9] are critical for making progress towards a sustainable future. [10][11][12] Bipolar membranes (BPMs) that demonstrate stable, high current-density operation under reverse bias have immense opportunity for implementation in such devices, due to their ability to sustain constant concentration, separated acidic and alkaline environments in a single device.…”

Bipolar membranes (BPMs) enable isolated acidic/alkaline regions in electrochemical devices, facilitating optimized catalytic environments for water electrolysis, CO2 reduction, and electrodialysis. For economic feasibility, BPMs must achieve stable, high current density operation with low overpotentials. We report a graphene oxide (GrOx) catalyzed, asymmetric BPM capable of electrodialysis at 1 A cm-2 with overpotentials < 250 mV. Experiments and continuum modeling demonstrate that the low overpotentials for water dissociation are achieved by deprotonation at GrOx catalyst sites located within the high electric field BPM junction region. The asymmetric nature of the BPM allows it to overcome water transport limitations due to its thin anion exchange layer, while maintaining near unity Faradaic efficiency for acid and base generation. Additionally, the asymmetric BPM exhibits voltage stability exceeding 1100 hours at 80 mA cm-2 and 100 hours at 500 mA cm-2 and its freestanding architecture implemented in an electrodialysis cell stack demonstrates its real-world applicability.
