Pore size distribution and capacitance in microporous carbons.

Modelling shows that the pore size distribution of microporous carbons determined by NLDFT only hides relatively small variations of the surface-related capacitance C/S between 0.7 and 1.3 nm.

Capacitance in carbon pores of 0.7 to 15 nm: a regular pattern.

The study of 28 porous carbons shows that the specific capacitance in the electrolyte (C(2)H(5))(4)NBF(4)/acetonitrile is relatively constant between 0.7 and 15 nm (0.094 ± 0.

Contributions of hemicellulose, cellulose and lignin to the mass and the porous properties of chars and steam activated carbons from various lignocellulosic precursors.

In this study, contributions of hemicellulose, cellulose and lignin to the mass and the porous properties of chars and activated carbons from various lignocellulosic materials were studied. A predictive calculation was established using the experimental results obtained for the three components separately to evaluate the carbonization and activation yields and their respective contributions to the chars and to the subsequent activated carbons of various precursors in term of weight fraction. These equations were validated.
