    摘要： The invention relates to physical chemistry and can be used for adjusting the rate of autocatalytic hydrogenation reactions. The method for producing a palladium-containing hydrogenation catalyst consists in reducing divalent palladium from the initial compound thereof and precipitating the thus reduced palladium on a carbon material, wherein, according to said invention, the initial compound is embodied in the form of tetra aqua-palladium (II) perchlorate. The reduced palladium is precipitated on a nano-carbon material which can be embodied in the form of fullerene C60, carbon nanotubes, cathodic deposit and the mixture of C60 and C70 fullerenes at the following ratio thereof: 60-80 mass % fullerene C60 and 20-40 mass % fluorine C70. The invention makes it possible to develop the method for producing a palladium-containing hydrogenation catalyst which exhibits a higher catalytic activity and operates in softer conditions (at a room temperature and a normal (atmospheric) pressure).

    摘要： The invention provides a nanometer sized carbon tubule enclosing a foreign material except for carbon. The carbon tubule comprises a plurality of tubular graphite monoatomic sheets coaxially arranged. The foreign material is introduced through a top portion of the carbon tubule. The introduction of the foreign material is accomplished after forming an opening at the top portion of the carbon tubule either by contacting the foreign material with the top portion of the carbon tubule together with a heat treatment or by an evaporation of the foreign material on the top portion of the carbon tubule together with the heat treatment. The foreign material is introduced only in a center hollow space defined by an internal surface of the most inner tubular graphite monoatomic sheet.
