Research

Our research bridges interfacial processes and electrochemical conversion devices through a multiscale framework spanning electrodes, interfaces, mass transport, electrolyzer scale-up, and product upgrading. At the electrode level, we design catalytic active sites to regulate reaction pathways for high activity, selectivity, and stability. Building upon these catalyst-level insights, we investigate the dynamic physicochemical processes occurring at the electrode–electrolyte interface under operating conditions, including charge transfer, double layer, interfacial heat and mass transport, and local chemical environment. Moving beyond interfacial process, we study multiphase mass transport within gas-diffusion electrodes and flow fields, elucidating how local transport of reactants, intermediates, products, and ions governs overall electrolyzer performance. By establishing mechanistic links between transport processes and electrochemical activity, we develop engineering strategies to overcome transport limitations at high operating current densities. These mechanistic and engineering insights together enable the scale-up of electrochemical systems, guiding the development of scalable electrolyzer architectures and industrially relevant operating strategies that translate laboratory discoveries into practical chemical manufacturing technologies. Together, our research establishes a continuous pathway from electrode engineering, interfacial science, and transport phenomena to electrolyzer scale-up and product upgrading, advancing the deployment of sustainable electrochemical technologies at industrial scale.
