TL;DR: In this article, the chemical structure of phosphorus species in two series of polymer-based and fruit-stone-based carbons obtained by phosphoric acid activation at 400-1000°C were investigated by XPS and solid state 31 P-NMR and 13 C -NMR.

TL;DR: Phosphorus-rich microporous carbons prepared by a simple H(3)PO(4) activation of three different carbon precursors exhibit enhanced supercapacitive performance in 1 M H(2)SO( 4) when highly stable performance can be achieved at potentials larger than the theoretical decomposition potential of water.

TL;DR: In this paper, a styrene-divinylbenzene copolymer was used to synthesize synthetic activated carbons and the resulting carbons were characterized by elemental analysis, cation exchange capacity measurement, infrared spectroscopy, potentiometric titration with calculation of proton affinity spectra, and copper adsorption from solution.

TL;DR: In this paper, the surface chemistry of activated carbon adsorbents was investigated by elemental analysis, cation exchange capacity (CEC, measured by neutralization of NaOH with acidic surface groups), infrared spectroscopy and potentiometric titration.

TL;DR: In this article, active carbons have been prepared from corncob using chemical activation with phosphoric acid at 400°C using varied ratio of impregnation (RI) using scanning electron microscopy.
