TL;DR: In this article, the mass fraction of volatiles, oxygen and the ratios of oxygen to carbon and hydrogen to carbon decreased linearly with pyrolysis temperature and the changes in surface charge were studied by ζ-potential measurements and were found to vary directly with the content of oxygenated functional groups.

TL;DR: In this paper, the effects of various vacancy and substitution defects in a coronene parent molecule have been systematically analyzed using density functional theory (DFT), and the impacts of these defects are best understood in terms of a reduced symmetry as compared to a “parent” coronene molecule.

TL;DR: The results indicated that the amount of oxygenated functional groups on the surface of biochars clearly differentiated the Biochar functionalities and porosity in terms of hydrophilicity, with the oxidized biochar being superior, followed by the low-temperatureBiochars, while the high temperature Biochars possessed lowest hydrophILicity.

TL;DR: In this article, the effects of pyrolysis temperature on biochar to oxidation by air were investigated and the surface properties of resultant biochars were examined to better understand how pyroplysis temperatures and feedstock sources relate to the development of surface characteristics.

TL;DR: In this article, the use of ozone to increase the cation exchange capacity (CEC) of two chars produced from pyrolysis of Douglas fir ( Pseudotsuga menziessii ) and a control bituminous coal activated carbon (AC) is reported.
