The catalyst plays a crucial role in activating the desired reactions by interacting with the reactant, intermediate, and product species. An active and stable catalyst is crucial in improving the efficacy of electrochemical conversions. Depending upon the operating temperatures, the bulk and surface of the catalyst materials can be involved differently in the catalytic processes. Under operating conditions, the catalyst bulk and surface usually undergo a significant restructuring process in response to the local reaction environment.

Our lab is interested in understanding the mechanism behind the dynamic bulk-surface restructuring processes and applying the new insight to design active and durable catalyst materials for high-temperature fuel cells and low-temperature electrolysis.
