The influence of various sol-gel preparation parameters both on gel formation and the textural properties and voltammetric response of the resulting ruthenium oxide aerogels are investigated systematically. The un-calcined ruthenium oxide aerogel in the amorphous phase possesses a surface area in excess of 350m(2) g(-1) has a specific capacitance as high as 595 F g(-1). (C) 2002 Elsevier Science B.V.
