چکیده

The pseudo-capacitance of RuO2, NiO, and MnO2 nano-particles supported on the various carbon nanofibers were examined. Among various CNFs, CNF with relatively higher crystallinity and better arranged edges on surface showed higher pseudo-capacitance than those with basal surface. Surface morphology and the particle size of metal oxide were characterized by HR-TEM and XPS. The electrochemical capacitance was evaluated using self-designed electrochemical experimental apparatus with cyclic voltammetry.

Studies on activated carbon capacitor materials loaded with different amounts of ruthenium oxide

Ruthenium oxide±carbon composites with different loadings of RuO2 on carbon have been synthesized by an electroless deposition process. Increase in RuO2 loading results in increasing the speci®c capacitance of the composite electrode. The effect of temperature treatment on the performance of these materials has been studied in detail. Maximum capacitance was observed after heat treatment at 100...

Effective Modified Carbon Nanofibers as Electrodes for Capacitive Deionization Process

Carbon materials have the advantages of good electrical conductivity and excellent chemical stability, so many carbon materials have been introduced as electrodes for the capacitive deionization (CDI) process. Due to the low surface area compared to the other nanocarbonaceous materials, CNFs performance as electrode in the CDI units is comparatively low. This problem has been overcome by prepar...

A Mathematical Model of OxideÕCarbon Composite Electrode for Supercapacitors

A pseudo two-dimensional model is developed for the general application of supercapacitors consisting of an oxide/carbon composite electrode. The model takes into account the diffusion of protons in the oxide particle by employing the method of superposition. RuO2/carbon system is modeled as a specific example. From the simulation data, it is found that the oxide particle size and proton diffus...
