Article Abstract
The development of suitable support to maximize the atomic utilization efficiency of platinum is of great significance for the hydrogen evolution reaction (HER). Herein, we report a simple and fast nonequilibrium-corrosive approach to prepare oxygen defect-enriched FeO decorated with trace Pt onto nickel-iron foam (Pt/FeO-O/NIF). The Pt/FeO-O/NIF electrode is superhydrophilic with intimate contact with the electrolyte. In addition, the strong electronic interactions between FeO and Pt and the oxygen-rich vacancies contribute to the catalytic process and improve the electrochemical interfacial properties. Thus, the Pt/FeO-O/NIF electrocatalyst only requires an overpotential of 29 and 39 mV at 10 mA cm in alkaline freshwater/alkaline seawater, respectively, exhibiting superior HER activity. Furthermore, the anion exchange membrane water electrolyzer (AEMWE) owns low cell voltage of 1.86 V at 1000 mA cm and long-term electrocatalysis durability. This work provides an effective approach for designing efficient AEMWE electrocatalysts for hydrogen production.

Developing efficient and durable catalysts for the oxygen evolution reaction (OER) in acidic media is essential for advancing proton exchange membrane water electrolysis (PEMWE). However, catalyst instability caused by lattice oxygen (O) depletion and metal dissolution remains a critical barrier. Here, we propose an oxophilic-site-mediated dynamic oxygen replenishment mechanism (DORM), in which O actively participates in O-O bond formation and is continuously refilled by water-derived species.

A novel electrocatalyst, zirconium ferrite nanoparticles (NPs) (ZrFeO NPs), was synthesized through coprecipitation and calcination processes at 300 °C and 500 °C using iron rust. The ZrFeO NPs were used as catalysts for the hydrogen evolution reaction. Furthermore, these NPs in an alkaline medium exhibited superior properties of a fractional order supercapacitor, based on which a prototype device was fabricated to demonstrate its energy storage applications.

The keto-enol tautomerism, involving a reversible isomerization of the molecule, plays a critical role in organic synthesis, biological activity, and molecular-scale charge transport. It is therefore essential to manipulate the process of keto-enol tautomerism. Unlike typical ketones, β-diketones exist dominantly in the enol form and it is a great challenge to realize enol-keto tautomerism due to the formation of intramolecular hydrogen bonds in the enol form.

Unlabelled: Proton exchange membrane water electrolyzers (PEMWEs) are a promising technology for large-scale hydrogen production, yet their industrial deployment is hindered by the harsh acidic conditions and sluggish oxygen evolution reaction (OER) kinetics. This review provides a comprehensive analysis of recent advances in iridium-based electrocatalysts (IBEs), emphasizing novel optimization strategies to enhance both catalytic activity and durability. Specifically, we critically examine the mechanistic insights into OER under acidic conditions, revealing key degradation pathways of Ir species.
