“…9(b). The β value is lower compared with the reported carbon nanotubes [30], ZnO nanowires [31], ZnS nanowires [32], SnO 2 nanowires [33], WO x nanowires [34,35], B nanowires [36,37], and LaB 6 nanowires [38], but is equivalent to the CdS nanostructure arrays [39] and Fe 2 O 3 columnar arrays [40]. Recently, Chiu et al [5] reported that there is no emission density from SiO 2 nanowires, but good FE properties from platinum coated SiO 2 nanowires.…”

“…Normally, controlling the CNT structure and its growth is achieved through a series of experimental parameters such as process temperature, gas mixtures, pressure, flow rates, and catalytic materials used. Even for CVD methods, there are various different approaches, including general thermal CVD, floating catalyst CVD (FC‐CVD), aerosol‐assisted CVD (AA‐CVD), plasma‐enhanced CVD (PE‐CVD), and DC (direct current) plasma‐enhanced CVD (DC‐PEVCD) …”

This paper reviews over 100 articles related to the development of nanotubes, nanofibers, and nanowires as catalyst supports for proton exchange membrane fuel cells. Several different novel methods for support and catalyst synthesis are discussed in detail. The fabrication processes for these nanomaterial-supported platinum (Pt) catalysts, catalyst layers, and membrane electrode assemblies are also reviewed. On the basis of the literature review, several research directions for catalyst cost reduction, catalytic activity, and durability enhancement are

“…In particular, stainless steel (SS) is one of the most attractive conductive substrates, due to its low price and good processability. Recently, several efforts have been made to grow CNTs on SS substrates with [4–5] or without [6–7] the addition of an external catalyst. In particular, we have shown that the growth of high quality multiwalled CNTs on SS in the absence of an external catalyst is possible because the nanoscale roughness and the metallic nature of the substrate surface both act as an efficient catalyst/template in the synthesis of tubular nanostructures [7].…”

SummaryWe have taken advantage of the native surface roughness and the iron content of AISI-316 stainless steel to grow multiwalled carbon nanotubes (MWCNTs) by chemical vapour deposition without the addition of an external catalyst. The structural and electronic properties of the synthesized carbon nanostructures have been investigated by a range of electron microscopy and spectroscopy techniques. The results show the good quality and the high graphitization degree of the synthesized MWCNTs. Through energy-loss spectroscopy we found that the electronic properties of these nanostructures are markedly different from those of highly oriented pyrolytic graphite (HOPG). Notably, a broadening of the π-plasmon peak in the case of MWCNTs is evident. In addition, a photocurrent was measured when MWCNTs were airbrushed onto a silicon substrate. External quantum efficiency (EQE) and photocurrent values were reported both in planar and in top-down geometry of the device. Marked differences in the line shapes and intensities were found for the two configurations, suggesting that two different mechanisms of photocurrent generation and charge collection are in operation. From this comparison, we are able to conclude that the silicon substrate plays an important role in the production of electron–hole pairs.
