“…The experimental (002) peak-to-background ratio, also known as the R parameter, is used to determine the number of ordered graphitic sheets. As a result, this value is calculated to be ~2.4, which is smaller than the values reported in earlier research [ 46 ]. According to previous studies, porous carbons with lower R values are thought to be more effective in LIBs [ 12 , 47 ].…”

Lithium-ion batteries with high reversible capacity, high-rate capability, and extended cycle life are vital for future consumer electronics and renewable energy storage. There is a great deal of interest in developing novel types of carbonaceous materials to boost lithium storage properties due to the inadequate properties of conventional graphite anodes. In this study, we describe a facile and low-cost approach for the synthesis of oxygen-doped hierarchically porous carbons with partially graphitic nanolayers (Alg-C) from pyrolyzed Na-alginate biopolymers without resorting to any kind of activation step. The obtained Alg-C samples were analyzed using various techniques, such as X-ray diffraction, Raman, X-ray photoelectron spectroscopy, scanning electron microscope, and transmission electron microscope, to determine their structure and morphology. When serving as lithium storage anodes, the as-prepared Alg-C electrodes have outstanding electrochemical features, such as a high-rate capability (120 mAh g−1 at 3000 mA g−1) and extended cycling lifetimes over 5000 cycles. The post-cycle morphologies ultimately provide evidence of the distinct structural characteristics of the Alg-C electrodes. These preliminary findings suggest that alginate-derived carbonaceous materials may have intensive potential for next-generation energy storage and other related applications.

“…4c). The high-resolution C1s XPS spectrum of N-doped graphene/SnS composite shows two peaks at about 284.5 and 285.5 eV after fitting, which are corresponding to the C-C or C = C bonds and the C-O or C-N bonds, respectively [26] (Fig. 4d).…”

N-doped graphene/SnS composite as highperformance anode materials has been synthesized by a simultaneous solvothermal method using ethylene glycol as solvent. The morphology, structure, and electrochemical performance of N-doped graphene/SnS composite were investigated by transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectra, Fourier transform infrared (FTIR) spectra, X-ray photoelectron spectroscopy (XPS), and electrochemical measurements. The SnS nanoparticles with sizes of 3-5 nm uniformly distribute on the N-doped graphene matrix. The N-doped graphene/SnS composite exhibits a relatively high reversible capacity and good cycling stability as anode materials for lithium ion batteries. The good electrochemical performance can be due to that the N-doped graphene as electron conductor improves the electronic conductivity of composite and elastic matrix accommodates the large volume changes of SnS during the cycles.

Aniline oligomers are important in relation to one of the most important conducting polymers, polyaniline. In the present study, aniline oligomer microspheres have been prepared during oxidation of aniline with ammonium peroxydisulfate under alkaline conditions in 0.2 or 1.0 M ammonium hydroxide. They were subsequently converted to disordered nitrogen-containing carbons during heating to 650 °C in an inert atmosphere. Raman spectra confirm the transformation of the aniline oligomers into a material displaying two peaks assigned to graphitic and disordered modes. In contrast to polyaniline, which retains its morphology after carbonization, the microspherical morphology of aniline oligomers was completely destroyed and replaced by two-dimensional plates. The evolution of the new morphology was followed by scanning electron and optical microscopies, and the corresponding changes in molecular structure after heating are discussed on the basis of Fourier transform infrared and Raman spectroscopies. The process of carbonization was followed by thermogravimetric analysis. The degree of crystallinity observed by wide-angle X-ray scattering was reduced after the carbonization.
