| 中文摘要 | the deliberate tailoring of nanostructured metallic catalysts at the monolayer-level is an ongoing challenge and could lead to new electronic and catalytic properties, since surface-catalyzed reactions are extremely sensitive to the atomic-level details of the catalytic surface. in this article, we present a novel electrochemical strategy to nanoparticle-based catalyst design using the recently developed underpotential deposition (upd) redox replacement technique. a single upd cu replacement with pt2+ yielded a uniform pt layer on colloid gold surfaces. the ultrathin (nominally monolayer-level) pt coating of the novel nanostructured particles was confirmed by cyclic voltammetry and x-ray photoelectron spectra (xps). the present results demonstrate that ultrathin pt coating effects efficiently and behaves as the nanostructured monometallic pt for electrocatalytic oxygen reduction, and also shows size-dependent, tunable electrocatalytic ability. the as-prepared ultrathin pt-coated au nanoparticle monolayer electrodes reduce o-2 predominantly by four electrons to h2o, as confirmed by the rotating ring-disk electrode (rrde) technique. |
