摘要: Nanocrystalline Ru1-xNixO2 materials were synthesized by a solution method. Local structure around doped Ni atoms was characterized extended X-ray absorption fine (EXAFS) functions obtained from spectra acquired at Ni-K edge (8333eV). It found that ions are confined to the Ru site in RuO2 rutile-type crystal structure, and tend group entering neighbouring sites along body diagonal of rutile lattice. Such neighbourhood two may act as an active for oxygen evolution promoting simultaneous electron transfer absorbed molecule water. The refined Ni-O bond distances suggest oxidation state is between +2 +3.
