(a,b) TEM- and (c) HAADF-STEM images of the as-synthesized (a) PtDEN/CMPT, (b) PtDEN/SBA15 and (c) PtDEN/NS. TEM images of the thermally treated (d) Pt/CMPT, (e) Pt/SBA15 and (f) Pt/NS with identical Pt loading, and (g) their Pt particle size distribution compared with PtDEN. The thermal treatment was carried out by calcination in air at 550 °C for 4 h.
