Enhanced supercapacitance of multiwalled carbon nanotubes functionalized with ruthenium oxide

---

Abstract
In this study we report the pseudocapacitive behavior of multiwalled carbon nanotubes (MWNTs) functionalized with hydrous ruthenium oxide in 1 M sulfuric acid for supercapacitor applications.The entangled network of nanotubes which forms open mesopores and their chemical stability with a basal geometry makes them suitable for such applications.Oxidative treatment to generate oxygenated functional groups on the tube-ends and along the sidewalls enables facile derivatization by hydrous ruthenium oxide to enhance the inherent capacitance.A specific capacitance of 80 F/g is obtained after ruthenium oxide functionalization, which is significantly greater than that of pristine MWNTs (30 F/g) in the same medium.
