Electrochemical capacitance of nanoporous hydrous RuO2 templated by anionic surfactant
Abstract.
The nanoporous RuO2·3.38H2O was synthesized with a surfactant template using sodium dodecyl sulfate.
The surface area of the material amounted to 220 m2 g−1 while the maximum specific capacitance
obtained was 870 Fg−1 at a scan rate of 10 mV s−1. The specific capacitance of nanoporous RuO2·3.38H2O
electrode exhibits enhancement, compared with other porous RuO2 materials synthesized by different
methods. The nanoporous RuO2·3.38H2O is a very promising material for high performance capacitance.
