Abstract In view of the serious environmental consequences caused by the continuous increase in atmospheric carbon dioxide (CO2) levels, technologies for its conversion into value-added chemicals are a high priority field of study. In this context, the electrochemical reduction of CO2 (ERCO2) is considered a promising path because it allows the production of high demand chemical inputs. However, despite recent progress, substantial advances are still needed to meet the criteria of selectivity and efficiency for practical applications, especially in the production of desirable multi-carbon molecules, such as ethylene. The key to addressing these challenges and achieving efficient C-C coupling via ERCO2, lies in strategies with emphasis on the study of electrocatalysts, electrolytes, electrode/reactor configuration and elucidation of their corresponding mechanisms. In this PhD project, from an unprecedented perspective in the literature, we will study the electrochemical conversion of CO2 into organic multi-carbon molecules of high added value, through an approach involving metallic nanoparticles and multilayer catalysts, low-cost ionic liquids electrolytes and flow reactors. The effect of variables intrinsic to the system and problem fundamental aspects will be evaluated through simulations involving finite element method and system optimization guided by chemometric tools, minimizing the total project cost and generation of waste. | |
