a b s t r a c t Polyfurfuryl alcohol (PFA) derived activated carbons were prepared by the acid catalysed polymerization of furfuryl alcohol, followed by potassium hydroxide activation. Activated carbons with apparent BET surface areas ranging from 1070 to 2600m2 g−1, and corresponding average micropore sizes between 0.6 and 1.6nm were obtained. The porosity of these carbons can be careful…
Abstract Supercapacitors (also known as ‘ultracapacitors’) offer a promising alternative approach to meeting the increasing power demands of energystorage systems in general, and of portable (digital) electronic devices in particular. Supercapacitors are able to store and deliver energy at relatively high rates (beyond those accessible with batteries) because the mechanism of energy stora…
