Synthesis and Electrochemical Properties of CMK-3 with Particles of Nickel, Cobalt and Copper

Abstract

Mesostructured carbon material CMK-3 for electrodes of electrochemical capacitors was obtained by the method of template synthesis. In order to increase the capacitance characteristics, impregnation of metal ions (Co, Ni, and Cu) into the structure of mesoporous carbon CMK-3 was carried out. The structure of the obtained materials was studied by X-ray diffraction and gas adsorption. The study by TEM showed that highly dispersed, nanosized particles are metal oxides Co, Ni and Cu with the size of 30-50 nm. The particles are uniformly distributed inside the carbon material. Electrochemical characteristics were studied in aqueous electrolytes (1M KCl and 1M KOH). It has been established that the impregnation of metal ions increases in the specific capacity of the mesoporous carbon material by about 30 % (from 110 to 156 F/g) in KOH

“…Oxidized carbon samples were prepared from commercial graphite-like mesoporous carbon material (CM) Sibunit-4 (S4) and mesostructured CM CMK-3 (carbon mesostructured by KAIST), oxidizing them with oxygen in a mixture of 20 vol.% in N 2 in the presence of water vapor (70.1 kPa) at a given temperature (400, 450 • C) for 2 h [31]. The catalysts were prepared using the layer-by-layer deposition method.…”
