Physico-chemical and electrical properties of activated carbon cloths. Effect of inherent nature of the fabric precursor
Five different cellulose-based fabrics were used to prepare activated carbon cloths (ACCs) by phosphoric acid activation at pre-established experimental conditions, in an attempt to explore the effect of the precursor's nature on properties of the resulting ACCs. Characterization by elemental a...
