and the catalytic performance did not change notably after
used for five times as well as the structure and morphology
(Fig. S8), indicating its excellent stability.
AuPd nanowire networks with other compositions were
prepared homologously by changing the concentration of
precursors in the emulsion with MgCl2. Furthermore, the
compositions could be varied by changing the precursor
species, and PtPd nanowire networks (PtPd-NNWs) were also
fabricated (see SI). The AuPd NNWs with different
compositions and PtPd NNWs were characterized by TEM, EDS
elemental mapping, EXAFS and XRD, and the results were
presented in Figs. S9 and S10, respectively. Meanwhile, the
catalytic performances of AuPd NNWs with different
compositions and PtPd NNWs were also studied. As illustrated
in Table S2, the PtPd NNWs with high density of structural
defects also displayed high activity. However, AuPd NNWs with
molar ratio between Au and Pd of 1 : 1.5 or 5 : 1 exhibited
lower activity than that of 1 : 3, which showed that the
catalytic activity of AuPd NNWs was also depended on their
compositions. It is evident that the catalysis optimization of
bimetallic alloys relies on both the control over the
morphologies of nanocrystals and compositions.

In conclusion, bimetallic AuPd and PtPd NNWs exhibiting
different surface structures were successfully synthesized via
salt mediating in emulsion. The dispersed water droplets in
emulsions deformed in different degrees with various salts,
generating various templates for the formation and growth of
bimetallic metals. The as-prepared alloys showed correlation
between structural defects and catalytic activity for oxidation
of HMF. AuPd and PtPd NNWs displayed excellent catalytic
performances in selective oxidation of HMF to FDCA under
mild condition comparing with AuPd NPs, core-shell and TiO2
supported AuPd NPs. The enhanced catalytic activity of the
NNWs was attributed to the electronic structures originated
from the abundant structural defects, resulting in strong ability
to generate radicals. The method provides a way to construct
bimetallic alloys with controlled morphologies and structural
defects for enhanced catalysis.
