Mostly monolayer morphology of hBN nanoparticles in dispersions confirmed by AFM and Raman spectroscopy. It is shown that mechanochemical obtained nanocomposites based on polyaniline and nanostructured graphite (PAni/nG) characterized by values of specific capacitance (550 F / g), significantly higher than the total capacity of the initial components due to the presence nG, which can provide access to more redox active centers of PAni. It was established that the N-containing conjugated polymers (poly-5-aminoindol - PAIn and poly-8-aminoquinoline - PAQ) is electrocatalysts of reaction of hydrogen (RH) from water in acidic electrolytes. Joint pyrolysis of graphene materials (electrochemically obtained multilayer graphene - MLG or partially reduced graphene oxide - PROG) and these polymers were obtained N-modified graphene material (N-MLG, N-PROG) which contains to 4 wt. % of nitrogen. Established that N-PROG characterized by significantly lower overpotential RH, higher current density and lower direct Tafel slope. A number of nanoscale metal-organic hybrid perovskites (R-NH3PbHal3, where Hal - Cl, Br or I), the structure of which is confirmed by X-ray diffraction and infrared spectroscopy, obtained by new mechanochemical method. Established that the hybrid perovskites of C6H13NH3PbHal3 characterized by intense green photoluminescence.
