Surface structure plays a key role in the efficiency of heterogeneous catalysts and electrochemical processes at the solid-liquid interface. Heterogeneous catalysis in general and electrochemical catalysis in particular are commonly used in organic synthesis and have a very broad application prospective in solar-cells and biotechnology. At the same time, electrochemical processes are responsible for numerous physiological functions in living organisms, such as muscle contraction and neuron firing.
TERS offers a unique spatiotemporal characterization of photo- and electrochemical processes at the interfaces. My laboratory interested in unraveling electrochemical and electrocatalytic processes at the nanoscale using TERS. We anticipate that these findings will transform the understanding of numerous fundamental electrochemical processes, including 1) conversion and storage of energy, 2) plasmon driven electron transport, 3) electrocatalysis and photocatalysis, and 4) electron transfer in living systems.
