Abstract

A simple method is demonstrated to fabricate novel FeS₂ spheres with abundant pore canals from Prussian-blue. Impressively, the porous FeS₂ spheres exhibit excellent hydrogen evolution performance in both acidic and alkaline media, deverling an overpotential of 136 mV and 158 mV to attain a current density of 10 mA cm⁻² in 0.5 M H₂SO₄ and 1.0 M KOH, respectively.
