“…In 2003, Mao and co-workers started to investigate the reconstruction and restructuring processes of Au single-crystalline electrode surfaces in a neat non-chloroaluminate alkylimidazolium-based ionic liquid. [65] These works are representative of the initial stages of in situ characterization of interfacial electrochemistry in ionic liquids. Despite difficulties in achieving high-resolution STM images in ionic liquid, atomic- [64,66,67] and molecular-resolution [22,29,68,69] imaging has been achieved for some systems.…”
