Size effect of Pt nanoparticles on the catalytic oxidation of …
The size of Pt nanoparticle and morphology of the CeO 2 support were examined by TEM and HRETM. From Fig. 1 a and b and Fig.S1 (a, c, e and g), it could be found that the Pt nanoparticles in parent solution are monodispersed and the mean size is 1.3, 1.5, 1.8, 2.1 and 2.5 nm. After the loading process, the Pt particles become bigger as …
