7709 483 DMSN@AuPtCo 80 nm TEM The average particle diameter and central-radial pore size of DMSNs were around 80 nm and 11.5 nm respectively, which were found from scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, and nitrogen adsorption measurements.AuPtCo clusters having a diameter of around 2.2 nm were formed by in situ reduction and attached to the pore surfaces, as clearly shown by SEM , TEM , elemental mapping images , powder X-ray diffraction analysis and diameter distribution analysis.
