1068 | SiO2@Pt NPs | TEM | the silica seed nanoparticles exhibited excellent dispersity with a mean size of 53 ± 1.5 nm, and with the further growth of silica on the surface of seed nanoparticles, the resulting SiO2 nanoparticles reached a size of approximately 114 ± 3.4 nm (Fig. 1b). TEM illustrated that the mean size of the as-prepared Pt NPs was 3.0 ± 0.3 nm (Fig. S1). HRTEM showed that the lattice spacing of the Pt NPs was 0.23 nm (inset in Fig. S1), which corresponds to the (111) lattice facet of Pt crystals [37]. |
