Due to the lack of communication between our cooperators and us, we misused the electron microscope (SEM and TEM) images which were done by our cooperators in this paper. These electron microscope images are from nanoporous PtCo alloy sample obtained by chemical dealloying PtCoAl ternary alloy and will be published in future by our cooperator. Therefore, in this addition/correction, new and correct electron microscope images for nanoporous PtNi alloy sample are shown (Fig. 1). It can be observed that these rod-like structures are significantly connected together, forming a hierarchical porous structure with big voids formed by the removal of pure Al phase and nanopores formed by dealloying Al-based alloy phases. It should be mentioned that these aligned and connected rod-like structures (which is inherited from the master alloy) should be formed during the ternary master alloy preparation process by the melt-spinning technique.
