“…SEM and TEM were used to confirm the success of Pd adsorption to the N-doped SWCNTs in addition to determining the effect SDS and PVP have on the synthesis. The SEM images taken confirm attachment of Pd to the N-doped SWCNTs in the presence of PVP and SDS with an absence of PVP causing aggregation of the Pd with a small portionbeing deposited on the SWCNTs in random fashion[41] (Fig. 3).Figure 3(d-f)show the significant impact PVP has on the distribution of Pd over the N-doped SWCNTs with much smaller aggregations and more uniform spreading of Pd is seen at PVP:Pd ratios of 2.5:1 and 10:1 with larger aggregations seen at the higher ratio.…”

“…Nitrogen doping is the more popular of the two however B-doping has been used to provide an electrocatalyst for oxygen reduction reactions [35] and caused some speculation as to whether boron and nitrogen co-doping may be useful [36]. In any case, N-doping has been shown to apply to a variety of reactions including: oxygen reduction reactions [37][38][39][40][41][42], hydrogen evolution reactions [43], and biological reactions [44]. Additionally Ndoped SWCNT electrocatalysts have been applied in biosensing [45].…”

“…Additionally Ndoped SWCNT electrocatalysts have been applied in biosensing [45]. SWCNTs as a metal-free catalyst rather than a catalyst support as L-L. Wang et al did [41]. The N-doped SWCNTs synthesised by K. Aoki et al [42] were manufactured through dielectric barrier discharge in high pressure nitrogen instead of the conventional CVD method.…”

“…Although not discussed until this point the incorporation of nitrogen into the CNT structure causes some interesting changes to the CNT structure. It has been observed that the incorporation of nitrogen into the nanotube structure promotes a bamboo-like structure for the nanotubes [41,42,56]. TEM, EDX, EELS and XPS have been used to characterise the N-doped CNTs.…”

Great advances in semiconductor technologies continue to be made with the demand for cheap, non-toxic, easily processed and environmentally friendly technologies on the rise. Single-walled carbon nanotubes (SWCNTs) are viewed as a promising candidate that satisfies these criteria however proper doping of the SWCNTs to provide n-type behaviour has been a persistent issue. In recent years, great advances have been made in providing air stable and efficient n-type doping of SWCNTs. This review presents the most recent and promising methods of n-type doping SWCNTs highlighted for their simplicity and quality of electrical properties. The analysis and major applications of these semiconductors with a focus on thermoelectric devices and transistors are discussed.

“…The deposition of Pd NPs in N-doped CNTs has been described by Zhu and co-workers as catalyst in the Heck reaction and in the oxidation of benzyl alcohol. [91] N-doped CNTs were synthetized by a chemical vapor deposition with iron-containing SBA-15 molecular sieve as the catalyst and ethylene diamine as the N and C sources. Pd NPs were deposited by employing sodium dodecyl sulfate as a salt and polyvinylpyrrolidone as surface modified and a stabilizing agent.…”

The review considers the variety allotropes of carbon to be used as supports for palladium and investigation of the resulting catalysts for carbon‐carbon forming reactions with focus on the catalyst recovery and effect of the solvent, base and catalyst loading in the efficiency of reactions. Specially, carbon nanotubes, C60 and graphene allowed the covalent functionalization with different ligands for palladium facilitating a lower leaching. Magnetic iron nanoparticles can be easily covered by charcoal, graphene oxide and carbon quantum dots facilitating the recovery of the supported catalyst. These heterogeneous catalysts are able to activate even aryl chlorides in cross‐coupling reactions such as Suzuki‐Miyaura, Mizoroki‐Heck and Sonogashira‐Hagihara in organic but also in aqueous media. All these features favoured the applicability of the materials for industrial processes.

The rapid development of nanomaterials, particularly advanced hybrid nanoparticles, has made new opportunities for the design and fabrication of high‐performance metal‐based catalysts. However, generating metal nanoparticles of desired size without aggregation is an important challenge for enhancing the catalytic activity of metal nanoparticles supported in the host matrix. In this work, a hybrid nanoporous material, namely Pd nanoparticles@N‐heterocyclic carbene@ZIF‐8, with a high internal surface area was successfully prepared using a dispersed anionic sulfonated N‐heterocyclic carbene–Pd(II) precursor inside the cavities of zeolitic imidazolate framework (ZIF‐8) using an impregnation approach followed by reduction with NaBH4. The anionic sulfonated N‐heterocyclic carbene was found to be a superb ligand for the stabilization of Pd nanoparticles in the pores of ZIF‐8. The resulting system was applied to the Mizoroki–Heck cross‐coupling reaction, in which the catalyst showed high catalytic activity under mild reaction conditions.
