Methods of study – powder X-ray diffraction analysis, methods for study of adsorption of gases and vapors. electronic microscopy, element analysis, temperature-programmed desorption of ammonia, IR-spectroscopy, chromatography, NMR spectroscopy. In the results of the work new catalysts for quinoline hydrogenation by gaseous hydrogen were created on the basis of composites of nickel or cobalt nanoparticles which may be used instead of analogies based on platinum group metals. It was shown that the composite of metallic nickel and nickel boride with hydrolytically-sable porous coordination polymer of chromium(III), which formed in situ upon reduction of nickel(II) chloride in pores of the matrix by sodium borohydride, has high catalytic productivity in the process of quinoline hydrogenation by hydrogen. It was found that the composites of nickel- and cobalt-containing carboneous nanoparticles doped by nitrogen with porous carriers, prepared by pyrolysis of coordination compounds of respective metals at presence of the carriers, had high catalytic productivity in the processes of quinoline hydrogenation by hydrogen. It was found that porous carriers of natural origine - perlite and vermiculite - could be used as the carriers for pyrolysis of the coordination compounds for creation of quiloine hydrogenation catalysts, this finding is important for manufacturing of the catalysts for hydrogenation in industrial processes.
