7927 717 Fe2O3/CNTs TEM It is obvious that these nanoparticles are uniformly distributed with diameter of around 1 nm. When 15 cycles of Fe2O3 were applied, a higher density of nanoparticles with larger size of around 2 nm on CNTs was observed both in HRTEM (Figure 1E) and HAADF (Figure 1F) images. 24.5 U/mg
