7826 600 PtNPs@PCs TEM, SEM The prepared PCs and PtNPs@PCs were characterized by SEM and TEM, and the results were shown in Fig. 1. The SEM image of PCs (Fig. 1A) indicated that the obtained carbon materials were porous structure monolith aer the removal of MgO template. As shown in Fig. 1B, it can be seen that PtNPs were uniformly spread on the surface of the porous of PCs.
