The catalytic activity of nanostructured low percent (1%) Co-Ni catalysts on the basis of glass fiber (GF) prepared by a"solution combustion" (SC) method was *** catalytic activity of the prepared samples was studied in the reaction of dry reforming of methane (DrM) with *** obtained samples were characterized by a number of physico-chemical methods,including XrD,SEM,TEM,TGA and *** active component was shown to be dispersed in the near-surface layer of the support as nanoparticles of 10—20 nm in *** active component showed a Co3O4 or(Co,Ni)Co2O4 spinel structure,depending on the catalyst *** spinel structure of the active component interacted strongly with the carrier,providing resistance to carbonization,high catalytic activity toward DrM,and high activity and stability in oxidation reactions.

Changes of a 65Ni25Cu10A1203 catalyst consisting of Ni-enriched and Cu-enriched alloys were investigated in the bulk and on the surface during the growth of nitrogen-doped carbon nanofibers （N-CNFs） by decomposition of a 50%C2I-I4/50%NH3 mixture using in situ X-ray diffraction （XrD） analysis, ex situ X-ray photoelectron spectroscopy （XPS） and transmission electron microscopy （TEM） techniques. It was shown that N-CNF growth at 450-650 ℃is accompanied by dissolution of carbon and nitrogen in the Ni-enriched alloy, whereas Cu-enriched alloy remains inactive. A correlation between nickel and copper surface concentrations and properties of N-CNFs in relation to the nitrogen content was found. It was demonstrated that phase composition of the catalyst during N-CNF growth determines the type of N-CNFs structure.
