Summary: Electrochemical CO2 reduction is a promising technique for carbon capture and utilization to combat global warming. Extensive research has focused on catalyst improvement, reactor engineering, and electrode development, but a lack of understanding in fundamental electrolyzer behavior remains. By investigating the impact of product selectivity and current density on catholyte pH in bipolar membrane electrolyzers, researchers were able to operate the system under acidic conditions, producing formic acid instead of formate, a significant achievement in this field. This study helps bridge the gap in fundamental understanding and contributes to the development of more scalable systems for CO2 reduction.

Summary: Capturing and utilizing waste CO2 to produce chemical building blocks has gained significant attention. Amine and alkali base solutions are efficient for CO2 capture, while electrochemical CO2 conversion is a promising technology for reducing greenhouse gas emissions. However, the separate investigation of these two technologies has increased the overall costs. Integrating both technologies by directly utilizing the capture solution as an electrolyte is a highly promising approach, although it is limited by low Faradaic efficiencies and partial current densities.

Summary: Complex geometries for electrodes pose a challenge in electrochemical applications. Slurry electrodes utilize complex flow distributors to enhance charge transfer between the current collector and slurry particles. In this study, titanium-based flow distributors produced by indirect 3D-printing were used to further improve electron transfer in vanadium redox flow applications. The titanium static mixers were coated with graphite to enhance activity for vanadium redox reactions. Heat treatment of the electrodes significantly improved anodic and cathodic current peaks, and testing in a redox flow cell showed discharge polarization of 110 mA cm(-2).
