Preferential Deposition of Pt Nanoparticles Inside Single-Walled Carbon Nanohorns


  • This work was performed, in part, under the management of the Nano Carbon Technology project supported by NEDO. We also thank T. Azami and D. Kasuya for preparing SWNH samples.


Pt nanoparticles are incorporated in the three-dimensional nanospace inside single-walled carbon nanohorns using a simple colloidal preparation method. The Pt particles are preferentially deposited inside nanohorns and are located near the defects (see Figure).
