Nitrogen-doped carbon fiber sponges by using different nitrogen precursors: synthesis, characterization, and electrochemical activity
Nitrogen-doped carbon fiber sponges (N-CFSs) were synthesized using the aerosol-assisted chemical vapor deposition (AACVD) method involving the decomposition of nitrogen precursors with a mixture of ferrocene (C10H10Fe), thiophene (C4H4S), and ethanol (C2H5OH) at 1020 degrees C under H-2/Ar flow. As nitrogen precursors, pyridine (C5H5N), acetonitrile (CH3CN), urea (CH4N2O), and benzylamine (C7H9N) were used. The N-CFSs were characterized by scanning electron microscopy, transmission electron microscopy, Xray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and thermogravimetric analysis. The nanocarbon material involved in N-CFS formation depended strongly on the nitrogen precursor used in the synthesis. The N-CFS synthesized from the benzylamine-ethanol precursor displayed corrugated carbon fibers with a bimodal diameter of similar to 190 nm and similar to 320 nm. The N-CFS obtained from the combination of benzylamine-urea was formed by carbon fibers with a zigzagging behavior also with a bimodal diameter of similar to 85 nm and similar to 190 nm. The N-CFS made from benzylamine-pyridine precursors exhibited highly entangled wavy carbon fibers and Fe-based nanoparticles surrounded by graphite materials. In this case, the diameters were similar to 270 nm and 390 nm. The N-CFS made from acetonitrile-ethanol favored the formation of large-diameter carbon fibers (similar to 400 nm). Chemical surface analysis by XPS characterizations revealed the presence of different nitrogen doping (N-substitutional, N-pyridinic, and N-pyrrolic) and chemical functional groups (nitrogen oxide, amines, N-2, and amides). The analysis also revealed that N-pyrrolic doping, quinone, ester, and ether groups were dominant in all samples. The nitrogen concentration contained in the sponges was 0.21-2%. The XRD characterization demonstrated the presence of the non-symmetric peak for the (002) crystallographic graphitic plane, suggesting the presence of slightly expanded graphite material. Voltammetry measurements showed a high surface activity owing to the presence of N-doping and several chemical species attached to the carbon fiber surface. Here, additional peaks to that of the quinone appeared. (C) 2019 Elsevier Ltd. All rights reserved.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 62936-56-5. Product Details of 62936-56-5.
