Figure 11. (A) CV curves of Pt ultrathin films, bulk Pt, and Au in Ar-purged 0.5 M CH₃OH and 0.1 M HClO₄ solution at a scan rate of 10 mV s^-1. (B) The same voltammetric cycle scaled by H_UPD charge. (C) MOR CV of a Pt film grown using a single deposition pulse in Ar-purged 0.5 M CH₃OH and 0.1 M HClO₄ solution, with a scan rate of 10 mV s^-1 for ten cycles. (D) Pt 4f and Au 4f spectra for the Pt film formed via a single deposition pulse, both before and after ten CV cycles, using the specified upper potential limit.

(F) Scaled current and mass activity of Pt#/TiN at 0.8 V_RHE against the number of deposition pulses. This figure is quoted with permission from Byun et al.^[56].
