Study of the surface structure of nickel nanoparticles catalyzing filamentary carbon growth by EXAFS: adsorption of probe molecules

Abstract

This work is attempt to apply EXAFS technique using probe molecules for studying the surface of Ni catalysts for carbon production. It has been demonstrated that H2Se is suitable for the probe molecule method. It was shown that (100) and (110) planes of the nanocrystals of nickel catalysts providing formation of filamentary carbon are mainly formed by one-layer height steps.
