Designing plasmonically integrated nanoreactors for efficient catalysis

Abstract

Plasmonically coupled nanoreactors capable of harnessing light energy and efficiently transforming it to perform chemical reactions are in significant demand in the field of catalysis. The development of unique solution-phase synthesis techniques for engineering intricate nanoarchitectures by introducing multiple functionalities can dramatically improve the efficacy of these nanostructures. In this context, the precise modulation of the nanostructural features and the integration of other components with the plasmonic nanoparticles within an isolated nanoconfined reaction environment is the current state of the art for their synthesis. This account highlights our achievements in designing different synthesis strategies and elucidating the mechanistic pathways involved in the development of plasmonically integrated nanoreactors. The range of applications of these plasmonic nanoreactors, which employ plasmon-induced energy for catalytic transformations, is also discussed.

“…[17][18][19][20] As such, plasmon coupling between nanoparticles provides a powerful strategy to achieve highly tunable optical properties useful for various applications. [21][22][23][24] Fabrication methods for plasmonic nanoparticle assemblies can be divided into top-down lithographic techniques [25][26][27][28][29][30] and bottom-up chemical approaches. [31][32][33][34][35][36][37][38][39][40][41] Top-down techniques such as electron beam lithography allow for precise fabrication of the desired assembly structures.…”

“…Such collective properties include distance‐dependent spectral shifts, 9–11 near‐field enhancement, 12–14 chirality, 15,16 and optical magnetism 17–20 . As such, plasmon coupling between nanoparticles provides a powerful strategy to achieve highly tunable optical properties useful for various applications 21–24 …”

Crosslinking Mechanisms of Phenol, Catechol, and Gallol for Synthetic Polyphenols: A Comparative Review

“…Inspired by the mechanism, synthetic polyphenols developed from phenolic building blocks have been introduced. Polydopamine [9][10][11][12][13], poly(L-DOPA) [14], poly(norepinephrine) [15][16][17], poly(gallic acid) [18], and poly(tannic acid) [19][20][21] are typical examples; the materials showing similar physicochemical properties to the natural polyphenols have been successfully used as adhesives, optical materials, sensors, and other bioinspired applications [12][13][14]. Especially due to their excellent biocompatibility [22,23], biodegradability [24], and wet-adhesion abilities [25,26], the self-assembled phenolic building blocks have been successfully utilized as biomaterials, such as nanomedicine, antimicrobial coating, and tissue scaffold (Figure 1).…”
