Fe 2+ /Fe 3+ Cycling for Coupling Self‐Powered Hydrogen Evolution and Preparation of Electrode Catalysts
A novel Zn−Fe flow battery featuring an Fe 3+ reduction reaction (Fe 3+ RR)‐coupled zinc oxidation, and an Fe 2+ oxidation reaction (Fe 2+ OR)‐coupled hydrogen evolution reaction (HER) system as well, was established. This battery is capable of driving two Fe 2+ OR‐coupled HER systems in series base...

| description | A novel Zn−Fe flow battery featuring an Fe
3+
reduction reaction (Fe
3+
RR)‐coupled zinc oxidation, and an Fe
2+
oxidation reaction (Fe
2+
OR)‐coupled hydrogen evolution reaction (HER) system as well, was established. This battery is capable of driving two Fe
2+
OR‐coupled HER systems in series based on the above Fe
2+
/Fe
3+
cycling, for efficient self‐powered hydrogen evolution. Meanwhile, this Fe
2+
/Fe
3+
cycling enables the preparation of a multifunctional catalyst, Pt‐3@SXNS (siloxene nanosheet), by the Fe
2+
OR‐promoted dispersion of Pt nanoparticles on SXNS; alternatively, this support could be obtained by Fe
3+
RR‐assisted exfoliation using Fe
3+
from the anolyte of Fe
2+
OR‐coupled HER. The Pt‐3@SXNS catalyst exhibits excellent catalytic activities toward Fe
3+
RR in the Zn−Fe flow battery, HER, and Fe
2+
OR in the electrolyzer, which is attributed to the strong electronic interaction between Pt and Si. This work offers a new strategy for energy storage and low‐cost hydrogen production from acidic wastewater. |
