Here, we demonstrate that graphene oxide (GO) can act as a structure-directing agent for the formation of PtPd alloy concave nanocubes enclosed by high index facets. In the presence of GO, PtPd alloy concave nanocubes could be easily tailored by a simple hydrothermal reaction. In sharp contrast, only cubic PtPd alloy nanocrystals were obtained in the absence of GO. Moreover, compared to the unsupported PtPd nanocubes, the composition ratio of Pt to Pd changed significantly from 1 : 1 to 3 : 1…
