Recent advances in electrochemical atomic force microscopy will be presented, with a focus on deciphering in situ an electrocatalyst’s morphological, structural, electrical and chemical properties at nanometer- and atomic-scale resolution. Selected results include unraveling the surface structure of state-of-the-art electrocatalysts during CO2RR, COR, and OER, as well as probing ion-induced viscosity variations in nanoconfined electrolytes alongside with a material’s local electrical conductivity. Complementary spectroscopic approaches, including in situ ATR-SEIRAS and on-line DEMS, provide direct molecular-level insights into reaction intermediates and interfacial hydration layer structures during CO2RR. A perspective will be given on multimodal approaches for nanoscale catalysis and rational innovation of energy conversion materials.
