The 2D WS2 semiconductor character is confirmed by electronic and X-ray fluorescence spectroscopy. By means of mechanochemical method a series of electrically conductive nanocomposites based on polyaniline (PAni) and nanostructured molybdenum and tungsten disulphides (nMoS2 and nWS2) were obtained. It was established that the obtained materials can be used as active components of electrodes of supercapacitors (SC); the largest values of specific discharge capacities characterized by nanocomposites with the highest content of PAni in them: 610 and 580 F/g, respectively for nМоS2/PAni(75) and nWS2/PAIN(75). Symmetric SC based on these nanocomposites were created and their functional characteristics were tested. It was established that the hugh stability of such SC is due to a significant shift in the potential of the redox transition of the PAni to the state of pernogranilin into the anode region. A comparative analysis of the morphology, spectral and photocatalytic properties of samples of graphene-like carbon nitride (C3N4) obtained by liquid phase exfoliation of massive l-C3N4 and mechanochemically nano-structured m-C3N4 is carried out. It has been shown that under the conditions of light exposure AM1.5G the sample m-C3N4 exhibits photocatalytic activity in the processes of photocatalytic hydrogen evolution and photo-decomposition of the R6G dye due mainly to monolayer morphology, higher restorative potential, as well as more efficient allocation and transfer of photogenied charges. The effect of appearance of nanorods on AFM of images of various graphene-like nanoparticles deposited on the atomic-smooth surface of mica, which are pseudo-nanostructures and reflect the trajectory of moving nanoparticles under the action of the edge of the ACM probe during scanning, is revealed. It has been shown that in orde Product Description popup.authors popup.nrat_date 2020-04-02 Close
