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, 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.

TL;DR: In this article, the chemical structure of phosphorus species in polymer-based phosphoric acid-activated carbon SP800 was investigated by X-ray photoelectron spectroscopy and it was shown that most probable structure for phosphorus species is condensed phosphates bound to carbon lattice via C O P bonding.
