Conclusions
In the present work, we prepared Pt nanomaterials with gas
bubble method assisted template sacrifice (Double-template) electrodeposition.
NanoZnO provided attachment sites for CuNPs,
PtNPs and a compatible microenvironment for the absorption of
analyte molecule. CuNPs not only played a role as the replacement
reagent for PtNPs formation, but also the template for the electrodeposition.
These nanoparticles exhibited synergistic effect to
the increase of the surface areas, ability to promote electron transfer
and exhibited good electrocatalytic activity for H2O2 and N2H4.
The coalition of replacement action and template assisted electrodeposition
is a novel concept in nanotechnology. The present
study may pave the way for the synthesis of novel nanomaterial
with unique morphology and properties, which will be employed to
design novel electrochemical sensors with other systems. Further
works derived by the coalition of replacement action and template
assisted electrodeposition are on our schedule
