Here, a self-templating strategy is reported to synthesize Ni-Fe mixed diselenide cubic nanocages for the electrocatalytic oxygen evolution reaction (OER). The diselenide nanocages are derived from corresponding Prussian-blue analog nanocages, which are first obtained by treating the nanocube precursor with a site-selective ammonia etchant. The resulting Ni-Fe mixed diselenide nanocages perform as a superior OER electrocatalyst, which affords a current density of 10 mA cm-2 at a small overpotential of 240 mV; a high current density, mass activity, and turnover frequency of 100 mA cm-2 , 1000 A g-1 , and 0.58 s-1 , respectively, at the overpotential of 270 mV; a Tafel slope as small as 24 mV dec-1 ; and excellent stability in alkaline medium.||URI:||https://hdl.handle.net/10356/139800||ISSN:||0935-9648||DOI:||10.1002/adma.201703870||Rights:||This is the accepted version of the following article: Nai, J., Lu, Y., Yu, L., Wang, X., & Lou, D.
