“…Currently, one-dimensional carbon nanomaterials (1D-CNMs), such as carbon nanotubes and carbon nanofibers, provide many advantages in diverse applications [5][6][7]. For direct alcohol fuel cells (DAFCs), the use of 1D-CNMs as the metal catalyst support was reported to greatly enhance the electro-catalytic activity for alcohol oxidation, as well as its ability to protect from the degradation caused by carbon monoxide poisoning.…”

Noble-shaped carbon nanostructures which have a unique geometry, i.e., carbon nanofibers form along with the growth of the carbon tree branches were synthesized using C 2 H 2 /H 2 as source gases under a thermal chemical vapor deposition system. Bunch-type Ni clusters (several hundred micrometers in size) were used as the catalyst for the growth of noble-shaped carbon nanostructures on the Al 2 O 3 substrate. The characteristics of the carbon nanostructures were investigated under the condition of the different gas flow rate ratios of C 2 H 2 and H 2 . In case of a high C 2 H 2 /H 2 flow rate ratio, the predominant growth on the substrate was that of carbon tree branches. In case of a low C 2 H 2 /H 2 flow rate ratio, on the other hand, we obtained noble-shaped carbon nanostructures. The growth mode and the cause for the formation of the noble-shaped carbon nanostructures was suggested and discussed.

“…Common to all of the techniques, there is the involvement of transition metals, especially metals of iron-group elements (Fe, Co, Ni) and their alloys. The metals are indispensable for CNMs growth and they remain in the products [8,9]. For purification, methods such as chemical oxidation, physical separation, and those that are based on a combination of chemical and physical techniques were developed [10][11][12][13][14].…”

“…Therefore, graphene and their derivatives were investigated intensively as potential microwave absorbers recently1920. However, as we all know that CNMs such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs) are usually synthesized by the methods of electric arc discharge, laser evaporation and catalytic chemical vapor deposition212223. And the transition-metal catalysts are indispensable in these currently known methods, which makes the raw CNMs produced by these methods inevitably contain high concentration metal impurities.…”

In order to clearly understand the intrinsic microwave absorption properties of carbon nanomaterials, we proposed an efficient strategy to synthesize high purity metal-free carbon nanotubes (CNTs) over water-soluble K2CO3 particles through chemical vapor decomposition and water-washing process. The comparison results indicated the leftover catalyst caused negative effects in intrinsic microwave absorption properties of CNTs, while an enhanced microwave absorption performance could be observed over the metal-free CNT sample. Moreover, the results indicated that the microwave absorption properties could be tuned by the CNT content. Therefore, we provided a simple route to investigate the intrinsic properties of CNTs and a possible enhanced microwave absorbing mechanism.
