Extraordinarily efforts have been placed on developing novel electrocatalysts for transforming energy-relevant small molecules. Catalysts particles are stabilized by surfactants and supported on carbon materials. The roles of these molecular additives and heterogeneous supports are often considered negligible or worse yet, not considered at all. Herein, we demonstrate that cationic surfactants play a significant role in modulating the electrode-electrolyte interface during carbon dioxide reduction. We further illustrate that the type of carbon support affects the structural transformation of the metal surface. Moreover, we will present new strategies to probe the electrode-electrolyte interfaces in electrocatalysis using advanced electrochemical techniques such as in-situ vibrational spectroscopy and electrochemical impedance spectroscopy. Our studies highlight molecular strategies to tune complex heterogeneous interfaces and opens up new avenues for directing catalytic performance.<br/>
