“…Coupling reactions of Suzuki-Miyaura, Heck and Sonogashira were also efficiently catalyzed by Pd/MWCNT, as well as hydrogenation of the triple carbon-carbon bond. 314 The catalyst was re-usable and can work in aqueous media. Palladium, rhodium, and bimetallic Pd/Rh nanoparticles deposited directly on surfaces of functionalized CNTs were active catalysts for hydrogenation of olefins, for C-C bond formation, and for carbon-oxygen bond cleavage reactions.…”

For almost twenty years there has been an increasing interest in the use of nanostructured carbon materials as catalyst supports. 1-16 Following the nanotechnology wave, a wide variety of carbon nanomaterials has been investigated as catalyst supports, including fullerenes, CNTs, CNFs, carbon onions, nanodiamonds, FLG or GO. CNTs and CNFs, which constitute a new family of support offering a good compromise between the advantages of AC and high surface area graphite have been particularly studied. The main advantages offered by CNT or CNF supports are: 17 (i) the high purity of the material can avoid self-poisoning; (ii) the mesoporous nature of these supports can be of interest for liquid-phase reactions, thus limiting the mass transfer; (iii) the high thermal conductivity that limits hot-spots that can damage the catalyst; (iv) their well-defined and tunable structure; (v) their rich surface chemistry that offers numerous perspectives for adsorption and dispersion of the active phase; and (vi) the specific metal support interactions, due to high electrical conductivity of the support and to the tunable orientation of the graphene layers, that exist and that can directly affect catalytic activity and selectivity. The possibility to perform catalysis in a confined space is also of great interest. 6,18 From a theoretical viewpoint, graphene provides the ultimate two-dimensional model of a catalytic support. The reason is related to its high theoretical surface area (ca. 2630 m 2 g −1 ), high conductivity, unique graphitized basal plane structure and chemical tolerance. FLG,

“…On the contrary, heterogeneous catalyst systems have solved this main problem and can be easily separated from the reaction mixture. A lot of efforts have been made to synthesize recoverable catalysts, such as Pd nanoparticles 5–7 and Pd immobilized on silica nanoparticles, 8–11 graphene, 12–14 polymers, 15–20 carbon nanotubes, 21, 22 and dendrimers 23–26 . Furthermore, Pd has also been immobilized on metal–organic frameworks, 27 metal oxides, 28–30 metal oxide nanoparticles 31–34 and gold nanoparticles for the use in plasmon‐assisted cross‐coupling reactions, resulting in localized heating 35–37 .…”

Palladium functionalized gold nanoparticles were used in the past as a catalyst system in light induced cross‐coupling reactions, but with a main limitation of the recuperation. To overcome this problem, a palladium functionalized Fe3O4/Au core‐shell nanoparticle was successfully synthesized with a peak wavelength of 680 nm from the plasmon resonance of the gold shell. By the presence of the magnetite core, the nanoparticle catalyst can easily be removed using magnetic precipitation. This is accompanied with the advantage of having less valuable gold present in the system. The gold shell makes it possible to induce local heating using plasmon resonance. By this combination, it is possible to recuperate the catalyst system using magnetic precipitation and increase the control and safety of the reaction due to the presence of the light‐induced plasmonic heating. It was possible to perform light‐induced Suzuki cross‐coupling reactions using this catalyst system, but with a dependency of the substrate. It was found that an anionic substrate is repulsed from the negatively charged core‐shell nanoparticle. The catalyst was examined on its recuperation abilities and could be reused up to 5 cycles. At the catalytic site a temperature was reached between 40 °C and 45 °C. Despite the promising results of the Suzuki reaction, it was not possible to perform light‐induced Sonogashira reactions due to the insufficient heat generation at the catalytic site. Nevertheless, these results are promising in the development of an easily recyclable catalyst together with an alternative heating source, resulting in an increase of control and safety.

“…However, the recovery and reusability of the catalyst represent a key issue for the sustainable development of any catalytic process. Therefore, many efforts have been made to develop heterogeneous palladium‐based catalytic systems for Suzuki reactions, including the immobilization or stabilization of palladium nanoparticles on various types of supports, such as high‐surface‐area silica, carbon nanotubes, polymeric materials, metal oxides, dendrimers and magnetic nanomaterials …”

A novel heterogeneous Pd catalyst was synthesized by anchoring Pd(II) onto 4′-(4-hydroxyphenyl)-2,2′:6′,2″-terpyridine-coated Fe 3 O 4 (FMNPs@TPy-Pd). This catalyst has been demonstrated for the first time as a recoverable and reusable heterogeneous nanocatalyst in Suzuki and Heck cross-coupling reactions. The catalyst is very easy to handle and is environmentally safe and economical. FMNPs@TPy-Pd was characterized using transmission and scanning electron microscopies, X-ray diffraction, and Fourier transform infrared and energy-dispersive X-ray spectroscopies.
