Controllable galvanic synthesis of triangular Ag-Pd alloy nanoframes for efficient electrocatalytic methanol oxidation
Triangular Ag–Pd alloy nanoframes were successfully synthesized through galvanic replacement by using Ag nanoprisms as sacrificial templates. The ridge thickness of the Ag-Pd alloy nanoframes could be readily tuned by adjusting the amount of the Pd source during the reaction. These obtained tri...

Summary: | Triangular Ag–Pd alloy nanoframes were successfully
synthesized through galvanic replacement by
using Ag nanoprisms as sacrificial templates. The ridge
thickness of the Ag-Pd alloy nanoframes could be readily
tuned by adjusting the amount of the Pd source during
the reaction. These obtained triangular Ag–Pd alloy nanoframes
exhibit superior electrocatalytic activity for the
methanol oxidation reaction as compared with the commercial
Pd/C catalyst due to the alloyed Ag–Pd composition
as well as the hollow-framed structures. This work
would be highly impactful in the rational design of future
bimetallic alloy nanostructures with high catalytic activity
for fuel cell systems. |
