Amorphous carbon nanofibres inducing high specific capacitance of deposited hydrous ruthenium oxide

---

a b s t r a c t
Composites consisting of ruthenium oxide particles deposited on amorphous carbon nanofibres are prepared
by a repetitive impregnation procedure. The choice of amorphous carbon nanofibres as support
of amorphous ruthenium oxide leads to composites in which the deposited oxide consists of aggregates
of extremely small primary particles (1–1.5 nm-size) and showing high porosity (specific surface area of
450m2 g−1). This special deposition of the oxide seems to favour: (i) high oxide capacitance (1000 Fg−1)
at high oxide loadings (up to 20 wt%) and (ii) high capacitance retention (ca. 80% from the initial oxide
capacitance) at high current densities (200mAcm−2). Amorphous carbon nanofibres are suitable supports
for amorphous ruthenium oxide and perhaps for other amorphous oxides acting as active electrode
materials.
