Purpose: In presented work results of synthesis of carbon nanotubes decorated with platinum nanoparticles by organic colloidal process as an example of direct formation of nanoparticles onto CNTs are reported. Design/methodology/approach: Powder XRD and transmission electron microscopy were used for characterisation of the morphology of composite as well as the distribution of nanocrystals on the CNTs surfaces. Findings: TEM results confirm that CNT were homogeneous and clean, without any admixtures and carbon deposits. High efficiency of covering carbon nanotubes (without aggregation) by platinum nanoparticles by organic colloidal process was confirmed. Observed particles appear to have a narrow size distribution. HAADF images confirm homogeneous covering of carbon nanotubes. Large clusters as well as empty fragments were not observed. Research limitations/implications: Some properties of materials in nanoscale strongly depend on size and are significantly changed if that size is smaller than 100 nm. Majority of these effects were no described and explained so far, what is mainly follows that image the object at nanoscale is difficult. Practical implications: Carbon nanotubes decorated with platinum and other precious metal nanoparticles can be characterised with atomic resolution by scanning transmision electron microscopy. Originality/value: Results of characterisation of raw carbon nanotubes as well as carbon nanotubes decorated with platinum nanoparticles were demonstrated in this work.
