Synthesis, Structure, and Electrochemical Characteristics of Carbon Inverse Opals

Carbon structures with inverse opal lattice modified with nickel compounds are synthesized. The thermal treatment effect on phase composition of compounds is studied. The electrochemical characteristics of carbon structures as electrode materials in supercapacitors are measured for samples obtained from various organic precursors. A considerable contribution of Faraday reactions to the specific capacitance of a capacitor with composite-based electrodes is mentioned.
