The adsorption of phenol from dilute aqueous solutions by seven activated carbons and one non-porous carbon black is reported. It is confirmed that the equilibrium can be described by a modified Dubinin-Radushkevich-Kaganer equation, with exponent n

The characterization of non-porous surfaces by the BET and the DRK techniques should be complementary. However, the monolayer capacities Nam obtained by these techniques may be different, with trends for the adsorption of simple molecules on a given

It is shown that the combination of different techniques, based on the adsorption of vapors and on calorimetry, can lead to the unambiguous characterization of carbonaceous materials. The case of a microporous carbon black, with pores in the range 0.

The combination of adsorption and calorimetric techniques shows that the adsorption of CO2is a two-step process in the case of active carbons with large micropores (L > 1.2–1.5 nm). For smaller pores, on the other hand, one observes a uniform filli

It is shown that the adsorption of phenol and 3-chlorophenol from aqueous solutions, by basic active carbons and at an equilibrium solution pH below that of dissociation of the phenols, can be described by an equation of the DRK type with exponent n

This paper examines the surface-related capacitance C/S of carbons with average micropore widths between 0.73 and 1.80 nm, using 1–2 M H2SO4, 6 M KOH and 1 M (C2H5)4NBF4 in acetonitrile as electrolytes. Following corrections for pseudocapacitance e

The interpretation of the performance of electrochemical capacitors based exclusively on the textural features and surface chemistry of carbons can be insufficient, or even misleading, in the case of materials prepared at low temperatures (typically

A systematic study by complementary techniques shows that PET-waste from plastic vessels is a competitive precursor of carbon electrodes for supercapacitors. PET derived-activated carbons follow the general trends observed for highly porous carbons a

The study compares the structural and electrochemical properties of 12 porous carbons based on phenolic resins, using both aqueous (H2SO4) and aprotic ((C2H5)4NBF4 in acetonitrile) electrolytes. It appears that they fit into the general pattern obser
