Abstract Plasmonic materials can generate strong electromagnetic fields to boost the Raman scattering of surrounding molecules, known as surface-enhanced scattering. However, these are heterogeneous, with only molecules located at ‘hotspots’, which account for ≈ 1% surface area, experiencing efficient enhancement. Herein, we propose patterned plasmonic trimers, consisting a pair dimers bilateral sides and trap particle positioned in between, address this challenge. The trimer configuration...
Plasmon-induced oxidation has conventionally been attributed to the transfer of plasmonic hot holes. However, this theoretical framework encounters challenges in elucidating latest experimental findings, such as enhanced catalytic efficiency under uncoupled irradiation conditions and superior oxidizability silver nanoparticles. Herein, we employ liquid surface-enhanced Raman spectroscopy (SERS) a real-time situ tool explore mechanisms catalysis, taking decarboxylation p-mercaptobenzoic acid...
Abstract Plasmonic catalysis employs nanomaterials to mediate the conversion of photon energy into localized electromagnetic fields, hot carriers, and thermal energy, facilitating molecular transformations under mild conditions. Understanding mechanisms governing plasmonic effects is crucial for optimizing yield selectivity in catalysis. However, challenges persist elucidating role field due complex interactions among various contributing mechanisms. This study introduces Au@Al 2 O 3...
Surface-enhanced Raman scattering (SERS) is renowned for amplifying signals, with electromagnetic mechanism (EM) enhancement arising from localized surface plasmon resonances and chemical (CM) as a result of charge transfer interactions. Despite the conventional emphasis on EM plasmonic effects, recent findings highlight significance CM when noble metals appear smaller entities. However, threshold size metal clusters/particles corresponding to switch in SERS mechanisms not clear at present....
Abstract The electrocatalytic carbon dioxide reduction reaction (CO 2 RR) can be significantly improved by the presence of alkali metal cations, yet underlying mechanisms remain unclear. In this study, we developed clean Cu nanoparticles with tailored curvatures to modulate local concentration K + cations and investigate their effects on CO RR. adjustment particle curvature allows for direct control over cation concentrations within electrochemical double layer, enabling broad‐range...
