Electrocatalysis plays a key role in the energy conversion processes that are central to renewable energy technologies such as fuel cells and electrolyzers. My research focuses on the understanding of structure-activity relationships for electrocatalytic materials and the development of efficient electrocatalysts for energy conversion. In situ scanning probe microscopy (SPM) and synchrotron-based X-ray spectroscopy will be used to characterize the solid-liquid interface and reveal new active sites. Those understandings will then be used to guide the design and synthesis of electrocatalysts (e.g., metal nanostructures, 2D materials) for fuel cells and artificial photosynthesis (water splitting and CO2 reduction).
