Fullerenes average diameter

Platinum deposits on onionlike fullerenes (OLFs) were studied by Xu et al. (2006). The Pt particles dispersed uniformly on OLFs had an average diameter of 3.05 nm, smaller than the 4.10 nm on PlA ulcan XC-72 prepared by the same method, and exhibited a peak current for methanol electrooxidation 20% higher than that on Pt/Vulcan XC-72. 

The fine particles of the fullerenes are prepared by injection of fullerene in o-dichlorobenzene solution to continuously stirring ethanol [89, 90]. The fine particles of Qg have granular-type shape and the average diameter was estimated to be 270 nm (Fig. 18). The crystalline structure of the Cgg fine particles was confirmed by X-ray scattering and...
