Title: Mesoporous Iron Sulfide for Highly Efficient Electrocatalytic Hydrogen Evolution

Abstract

Here, we report a facile synthetic protocol to pre-pare mesoporous FeS 2 without the aid of hard template as an electrocatalyst for the hydrogen evolution reaction (HER). The mesoporous FeS 2 materials with high surface area were successfully prepared by a sol-gel method follow-ing a sulfurization treatment in an H 2S atmosphere. A re-markable HER catalytic performance was achieved with a low overpotential of 96 mV at a current density of 10 mA·cm 2 and a Tafel slope of 78 mV per decade under alka-line conditions (pH 13). These theoretical calculations indicate that the excellent catalytic activity of mesoporous FeS 2 is attributed to the exposed (210) facets. The mesoporous FeS 2 material might be a promising alternative to the Pt-based electrocatalysts for water splitting.
