Synthesis of the composites. Cu(OAc)2•H2O or CuCl2•2H2O and N-containing organic components (DAB or Phen) were fully dissolved in methanol under stirring at 60 ºС (masses of reagents and sample coders are presented in Table , Supporting Information). The Cu content in the composites varied from 0.8 to 16.2 %. Then Aerosil powder was added to the solution of copper complex and solvent was evaporated at stirring at 60 ºС until formation of dry powder. The powders were finely grinded, transferred into the ceramic crucibles, and placed in a tubular furnace, which was purged with argon for 15 minutes, then heated to 300-600 ºC depending on pyrolysis temperature (Table ) at certain heating rate (Table ), and kept at a set temperature for one hour in an argon atmosphere, then cooled to room temperature in argon.
