Mesoporous SiO2-Supported Pt Nanoparticles for Catalytic Application
Figure 4
TEM images of sample NP-100 before (a) and after (b) loading Pt nanoparticles, showing NP-100 with a narrow distribution of diameter around 100 nm and Pt nanoparticles as small dark spots. Pt nanoparticles whose size is 2 to 3 nm in diameter were well dispersed.
