represents an emerging class of efficient catalysts for advanced catalytic
applications due to their intrinsic surface area and high catalytic
activity. Here, we report the design and synthesis of hollow Pt–Ni–Co
nanodendrites (NDs) through selectively etching the Ni-rich core of
solid core–shell Pt–Ni–Co NDs used as starting
material. Moreover, the formation mechanism of solid core–shell
Pt–Ni–Co NDs was investigated in detail by tracing the
growth stages at different reaction timed. Impressively, hollow Pt–Ni–Co
NDs exhibit 4.2- and 6.7-times higher mass activity for methanol and
formic acid oxidation than that of commercial Pt/C, respectively.
