Fabrication of AgPt and Pt NPs with the Ag7nm/Pt1.5nm bilayers by annealing between 500 and 800 °C for 120 s. (a) – (d) Schematic illustration of the formation of AgPt and Pt NPs from the Ag/Pt bilayers. (e) – (j) Atomic force microscope (AFM) side-views. (e-1) – (j-1) Cross-sectional line profiles across the typical NPs in (e) – (j). (k) Summary plots of average diameter (AD), average height (AH). (l) – (m) RMS roughness (Rq) and surface area ratio (SAR). (n)-(o) Energy dispersive x-ray spectroscopy (EDS) spectra of the samples annealed at 500 and 650 °C. (p) Summary plots of atomic (at) % of Pt and Ag
