Ordered mesoporous TiC–C (OMTC) composites were prepared and served as catalysts for nonaqueous Li–O2 batteries. The OMTC cathodes showed high specific capacity, low overpotential and good cyclability. Furthermore, the discharge and charge processes were investigated extensively by XRD, XPS and in situ GC-MS methods.

The article describes the features of MoS2/mesoporous carbon nanocomposite creation and application as an electrode material for hybrid supercapacitors. The combination of these two materials improved the electrochemical characteristics in comparison with molybdenum disulphide or mesoporous carbon on their own; in particular the synergetic effect between them led to the reduction of internal resistance and increase of electric conductivity that are reflected in the maximum power of the capacitor. In spite of a large surface area of the mesoporous carbon obtained from the raw material of plant origin (2200 m2 g–1), the synthesized nanocomposite (430 m2 g–1) has almost twice higher specific capacity (57 Fg–1 and 110 Fg–1, respectively) due to the summary effect of EDL and faradaic processes in the material. The samples were characterized by X-ray difractometry (XRD), transmission electron microscopy (TEM), porosimetry, impedance spectroscopy, voltammetry, and chronopotentiometry.
