The influence of the pretreatment of carbon nanotubes (CNTs) on the deposition of Pt‐n noparticles is investigated. The results show that refluxing CNTs by the mixture solution of sulfuric and nitric acids, or immersing them in the H 2 O 2 solution are effective ways for depositing Pt‐nanoparticles on the CNTs. The hybrid process yields the best results and obtained the Pt‐nanoparticles with a size of about 3 nm on the CNTs surface.
