In situ synthesis of a Fe₃S₄/MIL-53(Fe) hybrid catalyst for an efficient electrocatalytic hydrogen evolution reaction

Abstract

By modulating the Fe3S4/MIL-53(Fe) ratio with a controlled partial sulfurization strategy, the Fe3S4(52.1 wt%)/MIL-53 hybrid catalyst with an ideal hierarchical nanostructure and composition exhibited high HER activity.

Heterostructured Inter‐Doped Ruthenium–Cobalt Oxide Hollow Nanosheet Arrays for Highly Efficient Overall Water Splitting

“…However, it remains a challenge to develop highly efficient catalysts to overcome the high overpotential caused by the sluggish kinetics of the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER) . Recently, transition‐metal‐based catalysts have been intensively investigated for efficient water splitting, aiming at replacing expensive Pt‐based HER and Ir‐based OER catalysts. In particular, transition‐metal oxides (TMOs) have attracted significant attention because of easy synthesis and readily adjustable composition and structure .…”
