It was established that mechanochemical synthesis of C6H13NH3PbI2Hal results to their nanostructurization as 2D or pseudo-2D structures, and in the case of IP - to the formation of crystalline products (monophasic for CsPbBr3). The nanocomposite based on polyaniline (PAni) and nanostructured graphite (nG) was obtained by mechanochemical method. It was established that PAni/nG15 (containing a 15 wt% of nG) has a "sandwich" structure which consist from the several- or monolayer graphene particles and nanostructured PAni macromolecule, that provide the high capacity of symmetric supercapacitors (SC) based on PAni/nG15 (~340 F/g at current density of 2 A/g), the cycling stability for at least 10000 cycles and high speed characteristics (up to ~310 F/g at current density of 30 A/g). It was obtained the film of nanocomposite based on electrochemically reduced oxide graphene, nitrogen-containing organic conjugated polymer - poly-o-phenylenediamine (N-CAP) and MoSx particles by means of electrochemical approach. It was shown that this nanocomposite is an electrocatalyst of hydrogen evolution from water in acidic electrolytes and demonstrates the synergy effect in the electrolytic hydrogen evolution. The Co-NC nanocomposite electrocatalysts of reaction hydrogen evolution were obtained through the joint pyrolysis of N-CAP (or a mixture of the appropriate monomers with oxidants), Co(NO3)2 and nanoscale carbon material (acetylene black, oxide graphene, multilayer graphene, carbon nanotubes), the best of this Nanocomposite has a starting hydrogen evolution potential ~ -160 mV (vs. RHE).
