Abstract

In artificial photosynthesis, photogenerated free electrons and free holes unfold their reactive power through “dark”, that is, not light-driven, but bias potential-driven electrochemical transformations. Molecular fuel bonds are generated by means of heterogeneous electrocatalytic bond making and breaking at a liquid electrolyte-solid electrocatalyst interface. This Session addresses the surface chemistry and surface reactivity of such electrocatalytic processes at the atomic scale. Topics covered include synthesis, operando characterization of catalysts and reactive intermediates and concomitant electrochemical performance;
