High power density electrodes for Carbon supercapacitor applications [PDF]

, 2005
This paper presents results obtained with 4 cm2 Carbon/Carbon supercapacitors cells in organic electrolyte. In the first approach, a surface treatment for Al current collector foil via the sol–gel route has been used in order to decrease the Al/active ...

Pore size distribution and supercritical hydrogen adsorption in activated carbon fibers [PDF]

, 2009
Pore size distributions (PSD) and supercritical H_2 isotherms have been measured for two activated carbon fiber (ACF) samples. The surface area and the PSD both depend on the degree of activation to which the ACF has been exposed.

A routine method for the semi-quantitative determination of porous carbonaceous material in wastewater matrices

Frontiers in Environmental Engineering
The EU directive 2024/1990/EU mandates a fourth treatment stage for micropollutant removal in wastewater treatment plants (WWTPs). Porous carbonaceous materials (PCMs) such as powdered activated carbon (PAC) and biochar are effective but require ...

Renewable activated carbon from wood-based gasification char: A comprehensive study on physical activation

Carbon Resources Conversion
Wood gasification produces gasification char (GC), a carbonaceous by-product with limited sustainable valorisation strategies. The physical activation of wood-based GC as a precursor has received insufficient attention, likely due to the inherent ...

Gasification chars and activated carbon: Systematic physico-chemical characterization and effect on biogas production

Heliyon
Gasification residues/chars (GR) and activated carbon (AC) are added to wastewater treatment processes mainly as a fourth purification stage, e.g., to adsorb heavy metals or pharmaceutical residues. However, the effects of GR or AC, which are transferred
