| 英文摘要 | Maximizing the platinum utilization in electrocatalysts toward oxygen reduction reaction (orr) is very desirable for large-scale sustainable application of pt in energy systems. a cost-effective carbon-supported carbon-defect-anchored platinum single-atom electrocatalysts (pt-1/c) with remarkable orr performance is reported. an acidic h-2/o-2 single cell with pt-1/c as cathode delivers a maximum power density of 520 mw cm(-2) at 80 degrees c, corresponding to a superhigh platinum utilization of 0.09 g(pt) kw(-1). further physical characterization and density functional theory computations reveal that single pt atoms anchored stably by four carbon atoms in carbon divacancies (pt-c-4) are the main active centers for the observed high orr performance. |
