The chemical industry is responsible for 30% of industrial CO2 emissions, which primarily arise from fossil-fuel combustion used to power thermochemical processes. The use of electrochemical or plasma processes to manufacture organic chemical commodities offers a pathway to integrating renewable electricity into chemical transformations and contributes to the decarbonization of this sector. This dissertation advances the understanding of electron-driven processes for organic chemical production through two complementary approaches: overcoming mass transport limitations in multiphase electrochemical reactors and exploring novel plasma electrochemistry routes for chemical synthesis.Industrial implementation of organic electrochemistry has been historically limited by mass transport limitations that constrain production rates and selectivity. Using the industrially relevant electrohydrodimerization of acrylonitrile to adiponitrile as a model reaction, I investigate how convection can be used to overcome mass transport limitations and improve reaction performance in multiphase flow reactors. Through systematic experimental studies and data-driven modeling, I demonstrate that the Sherwood number-rather than the specific method of convection-defines electrochemical performance for both forced liquid convection and bubble-induced convection. This insight enables performance prediction across different reactor designs and provides engineering guidelines for scale-up, showing that equivalent mass transport conditions yield equivalent selectivity and production rates regardless of convection mechanism. In multiphase flow reactors operating above the solubility limits of organic reactants, I investigate how flow regimes, reactor geometry, and operational parameters such as flow rates, volume fractions of organic reactants in aqueous electrolytes, and current density influence reaction performance. I find that bubble-induced convection generated during electrochemical operation dominates performance, enabling high selectivity at elevated current densities. Pareto analysis reveals optimal operating conditions and provides design guidelines for balancing production rate and energy efficiency.While conventional electrochemistry is constrained by reaction pathways involving electron transfer processes at the interface between metal electrodes and electrolytes, plasma electrochemistry offers a fundamentally different approach by replacing solid electrodes with ionized gas to create reactive plasma-liquid interfaces. I investigate plasma-water interactions to establish baseline behavior and characterize the chemical processes occurring at plasma-liquid electrolyte interfaces. Building on these insights, I explore plasma-organic interactions using acrylonitrile as a model compound to compare plasma-driven chemistry with conventional electrochemical processes. Systematic investigation reveals that non-Faradaic energy transfer processes dominate over conventional electron transfer mechanisms, with product yields exceeding theoretical electrochemical limits by up to 32-fold, demonstrating fundamentally different reaction pathways accessible through plasma-driven chemistry.Together, these advances provide both practical guidelines for optimizing existing electrochemical processes and fundamental insights into novel plasma-driven organic reaction pathways that expand the toolkit of reactor options for the electrification of chemical manufacturing.
