“…Up to now, CNTs can be also synthesized by a wide variety of other routes such as heat treating the polymer [21], flame [22,23], ion-beam irradiation [24], electrolytic formation [25], in situ synthesis [26], solar synthesis [27] and microwave irradiation heating method [28]. It is well known that the methods of CNTs synthesis mostly require metallic particles as a catalyst, and magnetic Fe, Co, Ni nanoparticles are the best catalyst for CNTs growth.…”

“…It was demonstrated that a suitable amount of PVP as surfactant was needed during the microwave-assisted reaction, to prevent the agglomeration. It can be thought that on the other hand, the nucleation of Ni was accelerated with microwave irradiation [15], on the other hand, PVP as surfactant could absorb and decrease the surface tension. Therefore the single particle was prevented from growing, and several particles were prevented from coming together with adding a suitable amount of PVP.…”

“…These include the arc discharge [8], laser evaporation [9] and chemical vapor deposition [10]. In addition, there are also reports of other preparation methods, such as the thermolysis [11], flame fusion process [12], optical method [13], in situ synthesis [14], solar synthesis [15] and the microwave irradiation heating method [16]. In this paper, the microwave-assisted polyol method was firstly utilized to prepare CNTs, and nano-sized nickel particles were used as a catalyst in the process.…”

CNTs with core-shell structure were successfully synthesized by a microwave-assisted polyol method, and magnetic Ni nanoparticles were employed as a catalyst. The preparation method is fast and simple. The structures, morphology and magnetic properties of the as-synthesized samples were investigated using Raman spectrometer, X-ray diffraction (XRD), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), respectively. The XRD results suggested that Ni particles used as a catalyst in our experiment were nano-sized. In this paper, magnetic Ni nanoparticles were employed as a catalyst, and an electric spark on metal Ni nanoparticles with the microwave eddy current effect could induce CNTs' formation with the further reaction. The length of hollow carbon nanotubes was micro-sized and the diameters of most of the CNTs were varying from 18 to 20 nm according to the TEM images. Magnetic measurements demonstrated that CNTs with core-shell structure indicated a characteristic ferromagnetic behavior compared with Ni nanoparticles. microwave-assisted, Ni catalyst, carbon nanotube, core-shell structure Citation:Ruan Z, Liu X S, Hu F, et al.

“…e SPVD technique, employed in "heliotron" solar reactors through the infrastructure present at CNRS-PROMES facility in Odeillo-Font Romeu, France [15], has been already used up to date to obtain metal oxide nanoparticles (TiO 2 polymorphs [16], ZnO, ZrO 2 , or mixt oxides [17]), and ceramic nanoparticles (titanates and zirconates) [18]. A limited amount of data is reported on carbonaceous nanomaterials' synthesis through SPVD [15,19,20], and up to our knowledge no reports exist up to date concerning the synthesis of palladium-containing nanomaterials through this method.…”

Palladium supported on carbon nanoparticles has been obtained on a specially designed ceramic catalyst, obtained by thermal spraying on a copper substrate, starting from Pd/C targets. Solar physical vapor deposition in argon, an environment-friendly and energy-efficient alternative to arc or chemical vapor deposition, has been employed as a means of target vaporization at CNRS-PROMES facility in Odeillo, France. e obtained nanoparticles have a spherical-porous morphology with diameters ranging from 50 to 120 nm and specific sorption areas of 50,000 m 2 /g. e XRD diffractograms indicate the presence of dominatingly crystalline short-range ordered graphene oxide layers, in contrast with the amorphous Pd/C starting precursor. e presence of palladium (0.6% wt.) at the surface of the nanoparticles was proved by the EDX and XRD analyses, making the synthesized material useful in applications such as catalysis or gas sorption.
