Abstract:
An EXAFS study has been made of the immediate environment of the nickel atoms in high-dispersity metal catalysts Ni/SiO2 obtained by reduction of surface allyl complexes of nickel in hydrogen at 380-750 degree C. It was found that the environment of the nickel changed as the particle size increased with increasing temperature of reduction. In the case of ultradisperse particles, the nickel is surrounded by atoms of nickel and oxygen; as the particle size increases, the fraction of nickel atoms in the first coordination sphere of the nickel increases.
