“…At a higher GS concentration, the excessive GS surfactants may spontaneously assemble into micelles by themselves, and excess GS may also increase the charge repulsion and restrict the PPy growth. 5 Therefore, the GS content played a vitally important role in governing the homogeneous formation of ultralong interconnected PPy nanowires. The water contact angle of PPy-GS prepared with different GS concentrations was also investigated to evaluate the wettability of PPy-GS in electrolytes.…”

This work demonstrated a straightforward strategy to fabricate ultralong interconnected polypyrrole (PPy-GS) nanowires with a gemini surfactant (GS) as a soft template and dopant. Pure PPy particles and a PPy nanowire doped with CTAB (PPy-CTAB) were prepared for comparison. The results showed that the electrochemical performances, conductivity, and morphology of PPy-GS could be significantly changed by changing the concentration of GS in the aqueous phase owing to the different self-assembly behaviors. When the molar ratio of pyrrole, APS, and GS was 1:1:0.4, an interconnected ultralong and uniform PPy-GS nanowire with the largest surface area, the smallest average pore size, the lowest contact angle, and the highest conductivity can be obtained, resulting in the formation of effective electrolyte transport channels and faster electron transport pathways. Compared with pure PPy particles and the PPy-CTAB nanowire, the incorporation of GS significantly enhanced the conductivity and specific capacitance of PPy-GS-40%. The conductivity of PPy-GS-40% was up to 13.54 S/cm compared with 1.17 S/cm for PPy particles and 3.84 S/cm for the PPy-CTAB nanowire. Also, the highest specific capacitance of PPy-GS reached up to 556 F/g at 1 A/g compared with 233 F/g for PPy particles and 397 F/g for the PPy-CTAB nanowire. A total of 85.4% of the initial capacitance was retained even after 2000 cycles at 1.0 A/g. The energy density and power density of the PPy-GS-40% symmetrical supercapacitor were 49.4 Wh/kg and 400 W/kg, respectively. The good electrochemical properties of the PPy-GS electrode suggest a tremendous potential in the high-performance electrode not only for supercapacitors but extensively for various energy storage applications.

“…We also have reported other hybrid electrode types including 1D-conducting polymers (1D-CPs) [126][127][128] , carbon 1D-NMs, and metal oxide-based 1D-NMs [129,130] , respectively. Although the component in each of this hybrid material was different, they focused only on the improvement of the cyclability and electrochemical performance of each supercapacitor.…”

“…Sivakkumar et al [126] showed that a PANI nanofibers/CNT-based cell achieved an initial specific capacitance of 575 F g −1 , which was higher than that of pure PANI-based cell (545 F g −1 at 1st cycle) over the same voltage range. Meanwhile, Wang et al [127] presented an excellent hybrid nitrogen-doped carbon nanowire/PPy nanowire electrode with a large specific capacitance of 207 F g −1 at 1 A g −1 in three-electrode systems and a good cyclic stability (98.5% over 50 0 0 cycles). Apart from the utilization of carbon-based 1D-NMs, metal oxide-based 1D-NMs and CPs have been used to fabricate novel electrode materials, of core-shell, or array architecture.…”

Chemoselective hydrogenation of nitroarenes to anilines is of great importance for the manufacture of pharmaceuticals, fine chemicals, and dyes. In this study, a series of metal-free N-doped carbon nanotubes (NCNTs) have been prepared by the carbonization of in situ polymerized pyrrole on CNTs. The concentration of pyrrole, pyrolysis temperature, and the outside diameter of CNTs were investigated to improve the catalytic performance. As characterized by Raman and X-ray photoelectron spectroscopy (XPS), the optimal catalyst (NCNTs-800) possessed a unique structure doped with the same content of pyrrolic N and graphitic N. The activity and selectivity of NCNTs-800 have been evaluated for the selective hydrogenation of substituted nitroarenes. Highly selective hydrogenation of the nitro group of 12 different substrates has been achieved on NCNTs-800, even in the presence of a fragile iodo group. The hydrogenation reaction on N-doped CNTs from polypyrrole involved a mixture of different hydrogen species including nonpolar H radicals. In addition, stability and recyclability of NCNTs-800 have been tested.
