Abstrakt: The article discusses the production of carbon-metal oxide catalytic systems from technical coniferous greenery by the pyrolytic method. A method has been developed for obtaining a composite material based on biochar from coniferous flour waste with iron and cobalt oxides and their mixtures. The formation of a nanoscale metal oxide coating on the surface of a carbon carrier from coniferous wastes is shown, and the phase composition of the material is studied. Scanning electron microscopy data show a uniform distribution of the metal oxide layer on the porous surface of the carbon substrate. Using X-ray phase analysis, it was found that an active layer is formed on the surface of the support, including both oxides and pure metals, which confirms that during the pyrolysis of the preform of catalytic systems, part of the oxides is reduced to pure metal. The influence of the resulting composite systems on the thermolytic decomposition of a model compound was studied. The study of the catalytic activity of the obtained materials shows that all metal-carbon systems accelerate the model thermolysis reaction relative to the carbon support, and bimetallic catalysts are the most efficient.
