(A) Fit of XPS spectra recorded in the Sn-3d-region [13] for carbon (Vulcan) supported PtSn nanoparticles: modified with H3PMo12O40 (PtSn/C_PMo12) and bare (PtSn/C) ones. Excitation energy: 650 eV. The Sn spectra were deconvoluted into two doublets of binding energy (BE), 485.81 and 486.94 eV, for metallic Sn and SnO, respectively. (B) Chronoamperometric responses recorded (in 0.5 M H2SO4 + 0.5 M ethanol) for bare and modified systems deposited on glassy carbon.
