Energy Storage, Renewable Fuels and Waste Remediation Our lab focuses on improving electrochemical processes to effectively use renewable electricity. Many renewable energy sources (solar, wind, etc.) provide electricity, but without an efficient or cost-effective method to convert the electricity to useful or storable products. Our goal is to develop processes to store energy, produce useful products such as transportation fuels or industrially-needed chemicals, and clean up waste streams varying from agricultural to low level nuclear waste. This includes experimental catalysis, electrocatalysis and photoelectrocatalysis, focusing on understanding how to drive reactions efficiently and selectively.

Current research thrusts focus on:

• Improving kinetics of charge transfer for redox flow batteries
• Converting sunlight or renewable electricity to fuels and chemicals
• Developing electrocatalysts for electrochemical wastewater remediation

To address these, we will develop new materials, find links between heterogeneous catalysis and electrocatalysis, and use in situ spectroscopy of catalysts/electrocatalysts under operating conditions to better understand surface chemical reactions.
