Fig. 4.9 a Schematic diagram of the selective preparation of Pt12 and Pt13 clusters using DPA-TPM
and DPA-PyTPM as templates, b HAADF-STEM images of Pt12 and c Pt13 clusters supported on
mesoporous carbon, The loading is 1 wt % Pt, the inset is a magnified image of the cluster, d the
ORR mass specific activity of the Pt12 and Pt13 clusters, the inset is the kinetic current density
of the Pt12 and Pt13 clusters at different loadings calculated according to Koutecky–Levich [149].
