The article discusses the innovative approach of using electrochemistry in tandem with flow reactors to facilitate the clean production of hydrogen and other valuable chemicals like bio-based polymers. Current electrolysis technologies for hydrogen production often rely on rare metals and environmentally harmful substances, making them energy intensive. By pairing hydrogen production with electrosynthesis in flow reactors, the process can become more environmentally friendly and energy-efficient. Shifting from batch to flow processing necessitates a deep understanding of reaction kinetics and conversion behavior under different operating parameters. Electrochemical measurements such as polarization curves and galvanostatic electrosynthesis in flow cells are crucial for monitoring key variables like flow rate, current density, electrode morphology, and substrate concentration. Techniques like high-performance liquid chromatography help in analyzing the derivatives produced during electrosynthesis, providing insights into biomass selectivity and conversion behavior. By coupling data on current, conversion, and Faraday efficiency, it becomes possible to precisely quantify reaction products and evaluate residual charges, thereby reducing potential explosion risks caused by side reactions. Overall, this integrated approach offers a promising pathway towards more sustainable and efficient production processes in the field of electrochemistry.
