It was found that the composite MoS2/C with increasing carbon content increases parameter of lattice c. In this composite Raman spectra revealed two intense phonon bands first order G and D at ~ 1591 cm-1 and 1354 cm-1, respectively, which are caused by inelastic scattering of light by fluctuations sp2-bound carbon atoms. Established that the molybdenum sulphide at a temperature of 650 °C is observed exothermic effect caused by desorption of oxygen and water. It is shown that the mechanical mixing nanoporous carbon disulfide molybdenum leads to a sharp increase in conductivity resulting composite. © 2016 Sumy State University.

The electrochemical system based on laser irradiated composite of nanoscale titanium dioxide/nanoporous carbon is formed, the charge accumulation processes in this system depending on the composition of the composite and the impact of the laser irradiation on these processes are studied. It is shown that the laser irradiation increases the specific capacity of the composite systems 50 times at the discharge current of 5 mA, which is a result of the emergence of new and modified guest positions in composite components. © 2014.

The optical and electrochemical properties of titanium disulfide / nanoporous carbon composite are studied for the purpose of its use in the energy storage systems. It is established that laser irradiation of the formed composite increases the specific capacity of the corresponding devices ten times and stabilizes the charge / discharge processes. © 2015 Sumy State University.
