“…The peaks located at 232.0 eV/235.1 eV and 233.1 eV/236.2 eV in Mo (3 d 5/2 /3 d 3/2 ) spectra correspond to Mo 5+ and Mo 6+ , respectively, which is in agreement with literature values 62 63 64 . In addition, the characteristic binding energy separation (Δ Mo 3 d ) between the Mo 3 d 5/2 and 3 d 3/2 doublet of Mo 5+ and Mo 6+ is ∼3.1 eV as observed previously in the literature for Mo 5+ and Mo 6+ ions 65 . These XPS observations show that similar oxidation states of POM clusters on CNT are present following SL and ESD.…”

The rational design of improved electrode–electrolyte interfaces (EEI) for energy storage is critically dependent on a molecular-level understanding of ionic interactions and nanoscale phenomena. The presence of non-redox active species at EEI has been shown to strongly influence Faradaic efficiency and long-term operational stability during energy storage processes. Herein, we achieve substantially higher performance and long-term stability of EEI prepared with highly dispersed discrete redox-active cluster anions (50 ng of pure ∼0.75 nm size molybdenum polyoxometalate (POM) anions on 25 μg (∼0.2 wt%) carbon nanotube (CNT) electrodes) by complete elimination of strongly coordinating non-redox species through ion soft landing (SL). Electron microscopy provides atomically resolved images of a uniform distribution of individual POM species soft landed directly on complex technologically relevant CNT electrodes. In this context, SL is established as a versatile approach for the controlled design of novel surfaces for both fundamental and applied research in energy storage.

“…4(a)-(d)). These doublet core-level binding energies i.e., 232.32 eV and 235.44 eV correspond to Mo-3d 5/2 and Mo-3d 3/2 , respectively, which are due to the spin-orbit splitting (Mo-3d) and are in good agreement with the values reported by the other workers for MoO 3 films [4,13]. Hence, it reveals that the electron beam evaporated MoO 3 films pertaining the six valence molybdenum (Mo 6+ ).…”

“…The reduction peak was associated with a deep coloration of the film while the bleaching process was marked by the oxidation peak. It is well known that the reduction process involves the injection of electron and cationic species into MoO 3 to form molybdenum bronze [17,47,48]. Since the test was conducted in 1 M LiClO 4 -PC electrolyte solution, we assumed that such a coloration/bleaching process was governed by the double insertion/ extraction of electrons and Li + ions.…”
