Fe‐Based Materials for Electrocatalytic Water Splitting: A Mini Review

In the last few years, the development of effective electrocatalysts hold fascinating importance towards scalable green hydrogen (H2) and oxygen (O2) production has become an appealing area of research. A good number of iron‐based catalysts have been designed and synthesized which can mediate water splitting under mild conditions with minimum energy requirements. In this review, recent progress on iron‐based electrocatalysts focusing on Oxygen Evolution Reaction (OER), Hydrogen Evolution Reaction (HER), and Overall Water Splitting (OWS) are summarized. Tactical designing, targeted synthesis with electronic tuning, efficiency as well as durability are discussed here. The review is comprehensive and our target is to promote the development of highly efficient economical catalysts, to make their way from the laboratory to market by replacing noble metal‐based electrocatalysts. This review systematically summarizes and highlights the recent developments in Fe‐based heterogeneous and homogeneous electrocatalysts toward water splitting. The benefits and drawbacks of MOFs and molecular electrocatalysts are discussed. Our target is to endorse the Fe‐based electrocatalysts, to make their way from laboratory to market by replacing noble metal‐based catalysts.
