      conditions.

AB  - Fuel cells are expected to be one of the most promising alternatives to the 
      increasingly scarce fossil fuels, and Pt is the most commonly used catalyst for 
      anodic and cathodic electrochemical reactions. To realize large-scale 
      commercialization, it is most urgent to improve the efficiency of Pt and reduce 
      the cost. Here, we synthesized an octahedral Pt-Ni-Ir yolk-shell catalyst through 
      stepwise co-deposition (SCD), surface-limited Pt deposition (SLPD) and 
      Ni-coordinating etching (NCE) processes. Experimental studies showed that the 
      catalytic activities of the as-prepared trimetal yolk-shell catalyst were several 
      times higher than that of the commercial Pt/C towards oxygen reduction and 
      methanol oxidization under both acidic and alkaline conditions. This work may be 
      extended to designing other multimetallic functional materials with complex 
      hierarchical nanostructures, which is conducive to greatly enhancing the 
      performance.
