HierarchicalControl of Plasmonic Nanochemistry inMicroreactor
2019
A microreactor that
can confine chemical reactions exclusively
in tiny vessels with the volume of ∼0.015 μm3 is introduced. Aluminum inversed hollow nanocone arrays (IHNAs)
are fabricated by a simple and efficient colloidal lithography method.
Ag and Au nanoparticles (NPs), as well as polypyrrole, grow exclusively
in the conic cavities under light illumination. The photocatalytic
effect arising from the plasmonic enhanced electric fields (E-fields) of IHNAs boosts the reactions and is in charge
of the submicrometer site-selectivity. By partially inhibiting light
to IHNAs, various hierarchical patterns at the macro-, micro-, and
sub-microscale are obtained, inspiring a facile patterning technique
by varying the light source. In addition, the Al IHNA films are transferred
to flexible and curved substrates with unchanged performances, showing
high flexibility for wide applications. Microreactors based on the
IHNAs will contribute to the control of chemical reactions at different
dimensions and offer great potentials in developing novel nanofabrication
techniques.
