“…66 catalytic activity for water splitting [67][68] and Fenton's reaction. 69 Even excitation of surface plasmon resonance in metallic nanoparticles has been observed at wavelengths as high as 1064 nm. [70][71] On the other hand, Halas et al 72 have shown that surface plasmon excited in the Au nanoparticle decays into hot electrons with energies that allow by energy transfer the dissociation of H 2 adsorbed on the Au nanoparticle surface.…”

SERS spectra showed the formation of the 4,4'-DMAB on the nanostructured Cu surface independently of the laser employed. For the sake of comparison SERS spectra of a self-assembled monolayer of the 4-ABT on Ag surfaces decorated with Ag nanostructures have been also obtained with the same four lasers. When using the 532 nm and 632.8 nm lasers, the 4,4'-DMAB is formed on Cu surface at electrode potentials as low as -1.0 V (AgCl/Ag) showing a different behaviour with respect to Ag (and others metals such as Au and Pt). On the other hand, the Surface-Enhanced Infrared Reflection Absorption (SEIRA) spectra showed that in absence of the laser excitation the 4,4'-DMAB is not produced from the adsorbed 4-ABT on nanostructured Cu in the whole range of potentials studied. These results point out the prevalence of the role of electron-hole pairs through surface plasmon activity to explain the obtained SERS spectra.

“…2,10,12,16,[30][31][32] Specifically, plasmonic noble metal nanocrystals have recently been found to enhance a number of chemical reactions due to localized surface plasmon resonances. [33][34][35][36][37][38][39][40][41][42][43][44][45] However, the nature of the mechanism of the plasmonic driven chemistry in the presence of hot electrons or charged species and the concurrent photoluminescence properties over plasmonic particles are not well understood. 33,37,46,47 This investigation's motivation essentially arises from the discovery of an unwanted real-time in situ nucleation and growth of Ag filaments on a-Ag 2 WO 4 crystals which was driven by an accelerated electron beam from an electronic microscope under high vacuum.…”

Why and how Ag is formed when electron beam irradiation takes place on a-Ag 2 WO 4 in a vacuum transmission electron microscopy chamber? To find an answer, the atomic-scale mechanisms underlying the formation and growth of Ag on a-Ag 2 WO 4 have been investigated by detailed in situ transmission electron microscopy (TEM) and field emission scanning electron microscopy (FE-SEM) studies, density (100) surface, are the most energetically favorable to undergo the diffusion process to form metallic Ag.Ab initio molecular dynamics simulations and the nudged elastic band (NEB) method were used to investigate the minimum energy pathways of these Ag atoms from positions in the first slab layer to outward sites on the (100) surface of a-Ag 2 WO 4 . The results point out that the injection of electrons decreases the activation barrier for this diffusion step and this unusual behavior results from the presence of a lower energy barrier process.

“…In addition, due to the high throughput and low energy requirements, a novel application of plasmonics in chemical reactions gains significant attention, as reported in works on dissociation of hydrogen15, 16 and water,17, 18 photochemical19, 20, 21, 22, 23 and plasmon‐driven chemical reactions,24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37 etc. SPs excited on the surface of gold or silver can non‐radiatively decay into so‐called hot electrons with a high energy between the Fermi and vacuum energy level 36, 37, 38, 39, 40.…”

Propagating Surface Plasmon Polaritons: Towards Applications for Remote‐Excitation Surface Catalytic Reactions

et al. 2015

View full text Add to dashboard Cite

Plasmonics is a well‐established field, exploiting the interaction of light and metals at the nanoscale; with the help of surface plasmon polaritons, remote‐excitation can also be observed by using silver or gold plasmonic waveguides. Recently, plasmonic catalysis was established as a new exciting platform for heterogeneous catalytic reactions. Recent reports present remote‐excitation surface catalytic reactions as a route to enhance the rate of chemical reactions, and offer a pathway to control surface catalytic reactions. In this review, we focus on recent advanced reports on silver plasmonic waveguide for remote‐excitation surface catalytic reactions. First, the synthesis methods and characterization techniques of sivelr nanowire plasmonic waveguides are summarized, and the properties and physical mechanisms of plasmonic waveguides are presented in detail. Then, the applications of plasmonic waveguides including remote excitation fluorescence and SERS are introduced, and we focus on the field of remote‐excitation surface catalytic reactions. Finally, forecasts are made for possible future applications for the remote‐excitation surface catalysis by plasmonic waveguides in living cells.
