Applications of Plasmon-Enhanced Nanocatalysis to Organic Transformations

Abstract

Localized surface plasmon resonance (LSPR) is a physical phenomenon exhibited by nanoparticles of metals including coinage metals, alkali metals, aluminum, and some semiconductors which translates into electromagnetic, thermal, and chemical properties. In the past decade, LSPR has been taken advantage of in the context of catalysis. While plasmonic nanoparticles (PNPs) have been successfully applied toward enhancing catalysis of inorganic reactions such as water splitting, they have also demonstrated exciting performance in the catalysis of organic transformations with potential applications in synthesis of molecules from commodity to pharmaceutical compounds. The advantages of this approach include improved selectivity, enhanced reaction rates, and milder reaction conditions. This review provides the basics of LSPR theory, details the mechanisms at play in plasmon-enhanced nanocatalysis, sheds light onto such nanocatalyst design, and finally systematically presents the breadth of organic reactions hence catalyzed.

A decennary update on applications of metal nanoparticles (MNPs) in the synthesis of nitrogen- and oxygen-containing heterocyclic scaffolds

“…Nanocatalysis has been recently employed for wide applications in nanotechnology, productions of fuels from biomass, wastewater treatment, bioelectrocatalysis, environmental applications, 29 sustainable applications in green synthesis, 30 and organic transformations. 31 Grönbeck et al recently summarized the mechanistic insight of nanocatalysis via computational methods, including density functional theory (DFT) and other computation tools. 32 Chemical characterization includes optical spectroscopy such as optical absorption spectroscopy, which includes UV-Vis spectroscopy, photoluminescence (PL), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy; and electron spectroscopy including energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), auger electron spectroscopy (AES), and ultraviolet photoelectron spectroscopy (UPS).…”

Synthetic Organic Transformations of Transition‐Metal Nanoparticles as Propitious Catalysts: A Review

“…Wang group reported the CuI nanoparticle-catalyzed synthesis of tetracyclic benzo[e]benzo [4,5]imidazo [1,2-c] [1,3]thiazin-6imine heterocycles 105 by S N Ar-type CÀ S, CÀ N bond formation from isothiocyanatobenzenes 104 and benzimidazoles 103 (Scheme 49). [36] The electron-donating group on benzimidazole gave higher yields than the electron-withdrawing group.…”

“…Moreover, CÀ C, CÀ N, Suzuki-Miyaura coupling and polymerization reactions were reported. [4] σ-HÀ H, σ-CÀ H and σ-SiÀ H bond activation by metal nanoparticles were also reviewed. [5] In 2019, Nasrollazadeh reports the state of the art and future challenges in green synthesis of copper NPs such as Cu NPs, CuO NPs, Cu 2 O NPs, CuS NPs, CuAl 2 O 4 and immobilized copper nanoparticles on the numerous supports such as Natrolite, bentonite, perlite, ZnO, MgO, MnO 2 , reduced graphene oxide (RGO), and Fe 3 O 4 by a wide range of plant extracts.…”

“…The detailed Contribution to the Topical Issue "Dynamics of Systems on the Nanoscale (2018)", edited by Ilko Bald, Ilia A. Solov'yov, Nigel J. Mason and Andrey V. Solov'yov a e-mail: ilia.solovyov@uni-oldenburg.de understanding and description of these structures, interactions, properties, functions and dynamics represent a veritable challenge for theoretical and experimental techniques, and recently the term Meso-Bio-Nano (MBN) Science [1] has been coined to describe the endeavor to establish new methods for the exploration of the dynamics of systems along various sizes and time scales. A thorough understanding of MBN systems allows for an exploitation of novel phenomena on the nanoscale leading to an optimization of existing processes such as nanocatalysis [2,3] or the exploration of novel applications e.g. involving radiation.…”
