Electrochemical stability of self-assembled monolayers (SAMs) on Au and Pt electrodes. (a) Cyclic voltammograms showing reductive desorption behavior of alkylthiol SAMs with varying chain lengths (C3, C6, C10), indicating enhanced stability with longer chains. (b) Apparent surface coverage as a function of potential (vs. RHE), highlighting oxidative stability trends; longer chains retain coverage at higher potentials. (c) Comparison of stable potential windows for different thiol-based SAMs on Au (gold) and Pt (gray) electrodes, with aromatic and bulky headgroups showing enhanced electrochemical resilience [89].
