The synthesis of rhenium-doped fullerene-like MoS 2 nano-particles (Re:IF-MoS 2) is described. Careful inductively coupled plasma mass spectrometry analysis reveals that the concentration of the rhenium atoms in the IF-MoS 2 lattice is more than 10-fold smaller than the weighted amount of this atom in the precursor powder. High resolution scanning transmission electron microscopy in high angle annular dark field mode is used to decipher the isolated rhenium atoms in the MoS 2 lattice and confirm that these atoms substitute for molyb-denum atoms. Scanning electron microscopy analysis shows that, in
