In this work, we investigate the molecular composition and nanostructure of gasification charcoal (biochar) by comparing it with heat-treated fullerene arc-soot. Using ultrahigh resolution Fourier transform ion-cyclotron resonance laser desorption ionization time-of-flight mass spectrometry, Raman spectroscopy, high transmission electron microscopy analyzed low tar content obtained from gasification. Mass spectrometry revealed no magic number fullerenes such as C60 or C70 in charcoal. The positive ion m/z 701, previously considered a graphitic part nanostructure, was found to be breakdown product pyrolysis not nanostructure. A higher distribution ions similar that thermally treated soot indicates they share Recent insights into formation all carbon reveal conditions are optimal for fullerenes, but instead, curved structures coalesce fulleroid-like structures. Microscopy spectroscopy support stacked, which explored using reactive dynamics simulations.
