of a Pt-based catalyst with desired nanoarchitectonics highly
favors an enhanced electrocatalytic performance. Herein unique yolk–shell
structures containing a Pt core and a mesoporous bimetallic PtRu shell
(Pt@mPtRu YSs) are newly synthesized by a facile approach. Profiting
from the spatially and locally separated accessible active sites on
the interior Pt nanoparticle and exterior mesoporous PtRu nanocages,
the Pt@mPtRu YSs show superior catalytic activity, durability, and
CO tolerance for the methanol oxidation reaction. This facile method
is very significant to the design of all-metallic yolk–shell
catalysts for various electrocatalytic applications.
