Abstract

Ultra high vacuum-spectroelectrochemistry was used to investigate the electrochemically generated Cu species in the ionic liquid (N-methylacetate)-4-picolinium bis(trisfluoromethylsulfonyl)imide, [MAP][Tf2N]. The diffusion of Cu+ across the surface of the ionic liquid was monitored in situ by X-ray photoelectron spectroscopy (XPS). A numerical procedure was developed to simulate the surface process from which, the apparent diffusion coefficient of Cu+ across the surface is estimated to be 3.5 × 10−5 cm2 s−1. Bulk diffusion process of Cu+ in [MAP][Tf2N] was investigated ex situ for comparison with the surface process.
