文摘

Carbon nanotubes can be functionalized by oxidation ofHNO₃ orH₂SO₄-HNO₃. Thelattershows a higher capability in producing a high density of surfacefunctional groups. Thesegroups can act as specific nucleation sites for a well-disperseddeposition of Pt clusters onthe surface of carbon nanotubes. These modified carbon nanotubematerials were investigated by TEM, XPS, and DRIFT. A deposition mechanism is tentativelyproposed anddiscussed.
