than the spherical NCs. While taking into account that
the spherical NCs possessed the smallest size, it was quite
interesting that they showed much lower activity compared to
the multipods and tetrahedra. This should be mainly ascribed
to the difference of surface structures of the Pd NCs. As is
known, surface defects including atomic steps and edges often

lead to higher catalytic activities. Since the spherical Pd NCs
resulted from a thermodynamically controlled growth process,
they exhibited the most stable surface, which disfavored high
performance in catalysis. On the contrary, the multipods were
generated via a kinetically controlled growth process, which
resulted in plenty of surface defects (as shown in Fig. 1G and
Fig. S5), leading to the highest catalytic activity. In the case of
tetrahedra, they were obtained under the condition between
thermodynamic growth and kinetic growth, leading to less
surface defects on surfaces compared to the multipods, and the
activity was between those of spheres and the multipods. It is
worth mentioning that the TOF for the hydrogenation of
cyclohexene catalyzed by the multipods could be as high as

secondly, it diluted citral and slowed the reaction. The overall

In conclusion, various morphologies of Pd NCs, including
spheres, tetrahedra and multipods with plenty of surface
defects, could be synthesized by changing the ratio of
AAAC/OAm used. The multipods and tetrahedra have much
higher catalytic activity than commonly used spherical Pd NCs
for the hydrogenation of citral and cyclohexene. Furthermore,
since OAm is one of the most important ligands in the
synthesis of various kinds of NCs, including semiconductor
