to the alloyed composition effect, the dissociation of adsorbed
O2 on the PtPdCu TPs also can be observably facilitated, thus
leading to the reduced polarization of the dissociated O atoms’
electroreduction.

Conclusions
Hierarchically branched PtPdCu TPs have been fabricated with
a high yield through a one-step synthetic method in an
aqueous solution. Different from previous multi-step synthesis
in organic solvents, the proposed method offers a simple way
to PtPdCu TPs. The PtPdCu TPs are very unique in their
branched exteriors, which are quite different from previously
reported tripods with smooth surfaces. The PtPdCu TPs show
superior catalytic performance for ORR, which can be
attributed to their spatially and locally separated branches and
tri-metallic compositions. The developed fabrication method is
very promising for future preparation of mutil-metallic tripods
with controllable compositions and desired functions beyond
electrocatalysis.
