“…The surface plasmon response (SPR) absorption band of Au/CNT composites is centered at 540 nm (curve 1, Fig. 2b), which is in line with the reported value for Au/CNT composites [23]. While the SPR absorption band of simplex Au NPs is centered at 595 nm (curve 2, Fig.…”

“…[15,16] Covalent coupling with (3-aminopropyl)triethoxysilane or polyethyleneimine was also reported. [17][18][19] Gold NPs on CNTs present often a broad particle-size distribution, typically 12-20 nm. [20] Theoretical studies have concluded that Au interactions with the graphite surface are weaker when compared to other metals.…”

Gold nanoparticles have been deposited on three kinds of carbon nanotubes (CNTs), including nitrogen‐doped CNTs, by three different methods, namely, impregnation, organometallic decomposition, and deposition–precipitation. The choice of the gold precursor, the support, and the preparation procedure is critical for the control of the size and location (on or inside the nanotubes) of the gold nanoparticles. These catalysts were tested for the selective oxidation of CO in a hydrogen‐rich atmosphere. We have shown that the use of nitrogen‐doped CNTs as a support permits one to reach much higher activity and selectivity at low temperaturethan with the other CNT supports. This catalyst also shows a good stability under reaction conditions without detectable sintering.

“…The UV–vis spectrum of the Au nanoparticles (Figure 5c) shows a peak at about 535 nm, indicating the presence of a plasmon absorption band. The enhanced optical absorption was observed due to the increased electric field in the active photoactive layer by excited localized surface plasmons around the Au nanoparticles [35,36]. The EQE of the devices with the Au-doped SCNT is higher in the whole visible spectral range than that of the device with the SCNT.…”

The power conversion efficiency (PCE) of single-wall carbon nanotube (SCNT)/n-type crystalline silicon heterojunction photovoltaic devices is significantly improved by Au doping. It is found that the overall PCE was significantly increased to threefold. The efficiency enhancement of photovoltaic devices is mainly the improved electrical conductivity of SCNT by increasing the carrier concentration and the enhancing the absorbance of active layers by Au nanoparticles. The Au doping can lead to an increase of the open circuit voltage through adjusting the Fermi level of SCNT and then enhancing the built-in potential in the SCNT/n-Si junction. This fabrication is easy, cost-effective, and easily scaled up, which demonstrates that such Au-doped SCNT/Si cells possess promising potential in energy harvesting application.
