a b s t r a c t The preparation and characterization of high-surface-area ruthenium oxide (RuO2)/multi-walled carbon nanotubes (MWCNTs) composite electrodes for use in supercapacitors is reported in this work. The RuO2/MWCNTs composites were prepared by the polyol process of RuO2 intoMWCNTsand by Ru annealing in air before mixed with MWCNTs. The chemically oxidized and annealed Ru nanoparti…
a b s t r a c t In this work, poly(amide imide) solutions in dimethylformamide were electrospun into webs consisting of 350nm ultrafine nanofibers. These nanofiber webs were used to produce activated carbon nanofibers (ACNFs), through stabilization and carbonisation–activation processes. Experimental results indicated that ACNFs activated at 800 ◦C afforded the highest specific surface …
A B S T R A C T Mesoporous carbon spheres serving as electrode materials for supercapacitors were synthesized by a facile polymerization-induced colloid aggregation method using melamines as a carbon precursor and commercial colloidal silica as a silica source for hard template. After the carbonization of as-formed resins-template composites at 1000 8C and the removal of the silica templa…
