摘要：

The surface modification of fluorine-doped tin oxide by the underpotential deposition of noble metals (Rh, Ru, Pd, Pt, and Au) strongly influences the rate of sulfide-polysulfide reduction at the SnO//2 electrode. X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy are used to characterize as-prepared and surface modified tin oxide preceding and following electrode operation. The noble metal coverages follow the relative ordering: Au, Pt less than Ru, Pd less than Rh, showing an identical trend as the observed enhancement effects.
