Research in the Guo group focuses on tuning and understanding electrochemical interfaces. Leveraging our expertise on nanomaterial synthesis, electrolyte design, electrochemical analytical tools, and in situ vibrational spectroscopy, we aim to precisely control and understand electrochemical interfaces at molecular level. Eventually, our goal is to unlock new insights into environmentally important processes, such as the electrochemical conversion of atmospheric CO2 and nitrate pollutants to value-added products.
