“…Introducing oxygen-containing groups by oxidation treatment is normally considered as a prerequisite to increase the hydrophilicity of CNFs and the wetness between the metal precursor and the CNF surface. Some investigators have studied the surface chemistry of carbon nanofiber by liquid-phase oxidants, e.g., concentrated HNO 3 , and demonstrated that largely carboxylic-and carbonyl-groups were formed on the surface of CNFs and the presence of these oxygen-containing groups were essential to successfully deposit the metal precursor on the oxidized CNFs [9][10][11].…”

“…Growing attention has been paid to carbon nanofibers (CNFs) or carbon nanotubes (CNTs) in heterogeneous catalysis due to their unique structures and potential applications [1][2][3][4][5][6]. A considerable progress has been achieved to tailor the well-defined nanostructures of these materials, viz., the graphitic platelet orientation, using catalytic decomposition of carbon-containing gases on selected metal nanoparticles at an elevated temperature [1,2,7,8].…”

Carbon nanofibers with different nanostructures are prepared by catalytic CVD at 873 K using different catalysts and carboncontaining gases. As-grown carbon nanofibers are treated in concentrated nitric acid to introduce oxygen-containing groups, and therefore, to anchor palladium. The TPD-MS method is used to determine the number of acidic oxygen-containing groups and the results show that the number of oxygen-containing groups was strongly dependent on the graphitic platelet orientation. TEM, CO pulse chemisorption, and ICP-AES are used to characterize carbon nanofiber supported palladium catalysts. The results show that palladium particle sizes and palladium loading are dependent on the amounts of oxygen-containing groups on carbon nanofibers. TPR results show that the interaction between the palladium and the oxidized carbon nanofibers can be tailored by the variation of graphitic platelet orientation. A linear correlation between the amount of acidic groups and the palladium loading are observed.

A nontraditional approach to the development of catalysts for low-temperature ammonia synthesis is considered. The approach is characterized by application of catalysts representing heterogeneous analogs of the known homogeneous nitrogen-fixing systems based on transition metal compounds and strong electron donors. The use of this approach led to the development of catalysts that considerably surpass in their activity (at atmospheric pressure) the industrial catalyst for the ammonia synthesis. Some of the developed catalysts are active in the formation of ammonia from dinitrogen and dihidrogen even at 110--150 ~ The mechanisms of activation and hydrogenation of dinitrogen over these new catalysts are discussed.
