The article discusses the production of catalytically active composite materials based on biochar from coniferous flour waste as well as nickel and copper compounds. The elemental composition of the support has been studied, and it has been shown that the developed method of composite thermolytic formation can be used to create a nanoscale metal oxide coating on the surface of a carbon support made from coniferous flour. Scanning electron microscopy data show that there is a uniform distribution of the metal oxide layer on the porous surface of the carbon substrate. X-ray phase analysis showed that an active layer including both oxides and pure metals is formed on the support surface. It has been found that during the pyrolysis of the preform of catalyst systems, part of the oxides is reduced to pure metal, which leads to the production of metal-carbon systems. The study of the catalytic activity of the obtained composites has shown that monometallic systems accelerate the model thermolysis reaction relative to a pure carbon support, and bimetallic catalysts are the most efficient.
