CORE-SHELL TYPE GOLD-RUTHENIUM OXIDE NANO-COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR

摘要

A core-shell type gold-ruthenium oxide nano-composite material, comprising gold nanoparticles in a core and ruthenium oxide coated on the outside thereof, the molar ratio of the gold nanoparticles to the ruthenium oxide being 1:0.2-0.8. The preparation method for the core-shell type gold-ruthenium oxide nano-composite material comprises steps of: adjusting the pH of a gold-containing solution to 8-12, and adding an organic solution of ruthenium acetylacetonate and then uniformly mixing the same, the gold-containing solution comprising gold nanoparticles, a cationic surfactant, and water, the concentration of the cationic surfactant in the gold-containing solution being 0.05 × 10^-3 to 1.5 × 10^-3 mol/L; and carrying out a hydrothermal reaction in the mixed solution at 100-120°C to obtain a core-shell type gold-ruthenium oxide nano-composite material.
