Table S6. Caicination condition and the Zn/Fe ratio calculated from EDX analysis depicted in Fig.

S5. Under air heat-treatment, Zn/Fe is close to 0.50, which is starting composition, on the other

hand, Zn/Fe decreases to 0.08~0.22 under Ar heat-treatment, which results indicates there are few

zinc-based species at the surface.
