Plasmonic excitations
decay within femtoseconds, leaving nonthermal
(often referred to as “hot”) charge carriers behind
that can be injected into molecular structures to trigger chemical
reactions that are otherwise out of reacha process known as
plasmonic catalysis. In this Letter, we demonstrate that strong coupling
between resonator structures and plasmonic nanoparticles can be used
to control the spectral overlap between the plasmonic excitation energy
and the charge injection energy into nearby molecules. Our atomistic
description couples real-time density-functional theory self-consistently
to an electromagnetic resonator structure via the radiation-reaction
potential. Control over the resonator provides then an additional
knob for nonintrusively enhancing plasmonic catalysis, here more than
6-fold, and dynamically reacting to deterioration of the catalysta
new facet of modern catalysis.
