“…Nevertheless, Violi and coworkers assumed that the temperature increase does not play a dominant role in the growth reaction. 75 Because the temperature of a NP is homogeneous over its surface, a thermally induced reaction would lead to isotropic and polarization-independent growth, which is in contrast to their observations.…”

Insight into plasmonic hot-electron transfer and plasmon molecular drive: new dimensions in energy conversion and nanofabrication

Localized surface plasmon resonance (LSPR) of plasmonic nanoparticles and nanostructures has attracted wide attention because the nanoparticles exhibit a strong near-field enhancement through interaction with visible light, enabling subwavelength optics and sensing at the single-molecule level. The extremely fast LSPR decays have raised doubts that such nanoparticles have use in photochemistry and energy storage. Recent studies have demonstrated the capability of such plasmonic systems in producing LSPR-induced hot electrons that are useful in energy conversion and storage when combined with electron-accepting semiconductors. Due to the femtosecond timescale, hot-electron transfer is under intense investigation to promote ongoing applications in photovoltaics and photocatalysis. Concurrently, hot-electron decay results in photothermal responses or plasmonic heating. Importantly, this heating has received renewed interest in photothermal manipulation, despite the developments in optical manipulation using optical forces to move and position nanoparticles and molecules guided by plasmonic nanostructures. To realize plasmonic heating-based manipulation, photothermally generated flows, such as thermophoresis, the Marangoni effect and thermal convection, are exploited. Plasmon-enhanced optical tweezers together with plasmon-induced heating show potential as an ultimate bottom-up method for fabricating nanomaterials. We review recent progress in two fascinating areas: solar energy conversion through interfacial electron transfer in gold-semiconductor composite materials and plasmon-induced nanofabrication.

“…Metal ion reduction on the surface of NPs may involve a more complex mechanism than simple reduction once near the surface, as diffusion times are longer than hot‐electron lifetime. In this way, either surfactants or small metal clusters in solution can play an important role . Site‐selective etching or metal deposition as well as polymerization have also been achieved with hot‐carriers …”

these components was mainly passive in nature. As such, plasmonic nanoantennas have been widely used to explore the surrounding chemical environments, to couple with nearby emitters, or to produce heat in nanoscale regions. [7][8][9][10] On the other hand, the ability and understanding of using light to trigger chemical reactions at bulk metal surfaces has been advancing consistently since decades before the advent of plasmonics chemistry. Photoexcited states at the bulk metal-molecule interface have been studied by a vast number of techniques; surface photochemistry is a much older field compared with plasmonic chemistry and, for many years, has been closely associated with other areas of research such as heterogeneous (photo)catalysis and femtosecond chemistry. [11][12][13][14] Recently, the possibility to actively induce photochemical reactions by using plasmonic metal nanoparticles opened new avenues for both the plasmonic chemistry and surface photochemistry communities. [15] It is not the intention of this Progress Report to cover areas recently reviewed nicely by other authors [16][17][18][19][20][21] but to offer a more fundamental point of view on hot-carriers in the broader context of surface photochemistry and plasmonic chemistry. As such, I will start by briefly describing the traditional uses of plasmonic nanoantennas, emphasizing the role of energy losses within metal nanoparticles, and the recent appearance of high-refractive index dielectric antennas as powerful tools for enhancing electric and magnetic fields with minimal losses. I will then move forward to introduce the basis of molecular reactivity in photochemical reactions on both bulk metal surfaces and metal plasmonic nanoparticles before highlighting the new possibilities of plasmon-driven photochemistry regarding bond selectivity, enhanced (quantum and chemical) efficiency, and spatial distribution of reactivity. Complementary approaches studying charge-transfer processes and electronic transitions at the metal nanoparticle-molecule interface are briefly touched upon. Finally, a roadmap of challenges and possible routes to be explored is provided. Metal and Dielectric Nanoantennas: the Role of LossesLocalized surface plasmon resonances (LSPRs) can be triggered after light impinges on a metal nanoparticle (NP). The incident Light-induced chemical reactions on bulk metal surfaces have been explored for more than 50 years. Light absorption at the metal surface plays a key role in inducing photochemical transformations of adsorbed molecules. Our current ability to control both the absorption cross-sections and the energy of absorbed light by metal plasmonic nanoparticles opens new pathways for the manipulation of photochemical reactions. Physical phenomena associated with the localized surface plasmon resonances, such as energetic surface states and intensified electric fields, force us to revisit our traditional understanding of photochemical reactions at metal surfaces. Long standing goals in the field -such as bond selectivity and increas...
