▎ 摘　　要

NOVELTY - Preparing high-load carbon type based noble metal catalyst involves dispersing 5-50 mg of carbon material in 15 mL of solvent, ultrasonically, adding 0.1-1 mL of 10 mg/mL ligand-coated metal nano- particle solution to the dispersion system containing carbon material and ultrasonically processing for 15 minutes-1 hour, removing the free nano-particles by means of centrifugation and solvent re-dispersion, namely obtain the high-load type noble metal catalyst. USE - Method for preparing high-load carbon type based noble metal catalyst. ADVANTAGE - The method uses the organic solvent system with different polarity as the load which makes each kind of carbon material appear larger surface the solution, so that the solution phase self-assembly strategy can make the nano- particle loaded on the surface material, the over- loading process is not affected by the type of the material size and dimension and used for noble metal catalyst in various fields and function used for preparing for various fields.
