8114 922 Ru/PC 1.46 nm TEM This has been firmly demonstrated by the transmission electron microscopy (TEM) image (Fig. 1b), in which plenty of Ru NPs with a small size (1.46 nm, Fig. 1c) are highly dispersed on the surface of the PC without obvious aggregation after the electroless deposition process.
