“…Several studies on plasmonic catalysis and LSPR‐mediated catalytic transformations have focused on the demonstration of this phenomenon, quantification of reaction rates, and investigation of plasmonic enhancement mechanisms towards a variety of transformations (oxidation, couplings and reductions, for example) . For instance, it has been demonstrated that the main mechanisms by which LSPR excitation can accelerate or mediate these transformations may occur due to localized heating and charge transfer (direct and indirect pathways) as a result of LSPR excitation ,,. Regarding transformations involving charge transfer of LSPR‐excited hot electrons and holes to surface adsorbates, a unifying treatment has been recently proposed .…”

Studies on surface plasmon resonance (LSPR) mediated catalytic transformations have focused on quantification of reaction rates and investigation on enhancement mechanisms. However, the establishment of structure-performance relationships remains limited. For instance, the importance of nanoparticle size remains overlooked, and relatively large nanoparticles (> 50 nm in size) are generally employed as catalysts. Herein, we unravel how plasmon decay pathways (absorption and scattering efficiencies) and electric field enhancements as a function of size dictate plasmonic catalytic performances. We employed Ag NPs having 12-50 nm in size as a proof-of-concept catalysts, and the LSPR-mediated oxidation of p-aminothiophenol to p,p'-dimercaptoazobenzene as a model reaction. Our data and simulations revealed that the LSPR-mediated activities displayed a volcano-type variation with size, which was dependent on the balance among near field enhancements, absorption, and scattering. As this transformation is driven by the chargetransfer of LSPR-excited hot-electrons to adsorbed O 2 molecules, the variations in the optical absorption as a function of size represented the dominant contribution to the plasmonic catalytic activities. We believe our results shed important insights over the optimization of physical and chemical parameters in plasmonic nanoparticles in order to maximize plasmonic catalytic activities.

“…This multifunctional nature of plasmonic substrates enables a unique platform that combines the capabilities of energy harvesting from visible light, photocatalytic functions, and ultrasensitive characterization of molecular events in the same design [4,[11][12][13][14][15]. The integration of plasmonic substrates with stimuli-responsive biological materials promises countless self-powered nanobiological systems with precise positional control of selectively stimulated molecular events.…”

We have reported the in situ surface-enhanced Raman spectroscopy (SERS) monitoring of repetitive surface plasmon-mediated chemical transformation cycles in a conjugate nanobiological system. The nanobiological conjugate comprised a gold-coated plasmonic substrate biofunctionalized with thiolated single-stranded DNA carrying a reduction-oxidation indicator methylthioninium chloride, which is also known as methylene blue (MB), in buffer solution at a neutral pH. Exposure to a 523-nm laser excitation produced pronounced SERS bands of oxidized MB. Continued exposure to the laser resulted in disappearance of the SERS bands, which can be interpreted as a reduction of MB. This occurred in the absence of electrochemical stimulation, chemical agents, or catalysts, suggesting a surface plasmon-mediated mechanism of the transformation. The oxidized form of MB was recovered by an addition of fresh buffer solution on the surface of the sample. Continued laser exposure with periodical addition of the buffer resulted in repetitive cycles of changes in the SERS pattern, which were monitored in situ. The chemical transformations of MB were preceded by a buildup of an intermediate SERS pattern, which was attributed to a transient form of MB created by selective surface plasmon-driven excitation.

Recent advances in surface plasmon-driven catalytic reactions

Abstract: Surface plasmons, the free electrons' collective oscillations, have been used in the signal detection and analysis of target molecules, where the local surface plasmon resonance (LSPR) can produce a huge EM field, thus enhancing the SERS signal.
